Due to breaking changes in react-native, the version given in the left column (and higher versions) of react-native-svg only supports the react-native version in the right column (and college versions, if possible).
It is recommended to utilise the version of react given in the peer dependencies of the react-native version y'all are using.
The latest version of react-native-svg should always piece of work in a clean react-native project.

Or, include this PR manually for v7+ stability on android for older RN ( included in 0.57-stable and newer).
The latest version of v6, v7, v8 and v9 should all work in the latest react-native version.
v7 and newer requires the patch for making android thread safe, to get native animation back up.
Manually
Android pre RN 0.60
-
yarn add react-native-svgIn RN 0.60+, this is all you lot should ever need to practise get Android working. Before this, react-native link was responsible for the following steps: -
Suspend the following lines to
android/settings.gradle:include ':react-native-svg' project( ':react-native-svg' ).projectDir = new File(rootProject.projectDir, '../node_modules/react-native-svg/android' )
-
Insert the post-obit lines inside the dependencies block in
android/app/build.gradle:implementation project( ':react-native-svg' ) -
Open up up
android/app/src/main/java/[...]/MainApplication.java
- Add together
import com.horcrux.svg.SvgPackage;to the imports at the top of the file - Add
new SvgPackage()to the list returned by thegetPackages()method. Add a comma to the previous particular if there'south already something at that place.
iOS pre RN 0.60
Transmission linking
To install react-native-svg on iOS visit the link referenced to a higher place or exercise the following (react-native link should do this for you):
- Open up your project in XCode and drag the
RNSVG.xcodeprojfile (located in.../node_modules/react-native-svg/ios) into the Libraries directory shown in XCode. - Expand the
RNSVG.xcodeprojfile you lot merely added to XCode until you see:libRNSVG.a(located inRNSVG.xcodeproj>Products) - Drag
libRNSVG.ainto the Link Binary With Libraries section (located in Build Phases which may be found at the top of the XCode window)
CocoaPods
Alternatively, yous can use CocoaPods to manage your native (Objective-C and Swift) dependencies:
- Add RNSVG to your Podfile (with RN 0.60+ autolinking, this is not needed)
pod 'RNSVG' , :path => '../node_modules/react-native-svg' If cocoapods is used and if error RNSVGImage.m:12:9: 'React/RCTImageLoader.h' file not institute occurs:
Add together the following entry in Podfile:
pod 'React' , :path => '../node_modules/react-native' , :subspecs => [ [...] 'RCTImage', # <-- Add RCTImage ] and run pod install from ios folder
Troubleshooting
Problems with Proguard
When Proguard is enabled (which it is past default for Android release builds), it causes runtime error. To avoid this, add together an exception to android/app/proguard-rules.pro:
-keep public class com.horcrux.svg.** {* ;} If you lot have build errors, then it might exist caused by caching bug, please effort:
watchman watch-del-all rm -fr $TMPDIR/react-* react-native outset --reset-enshroud Or, rm -rf node_modules yarn react-native first --reset-cache Unexpected behavior
If you have unexpected behavior, delight create a clean project with the latest versions of react-native and react-native-svg
react-native init CleanProject cd CleanProject/ yarn add react-native-svg cd ios && pod install && cd .. Make a reproduction of the problem in App.js
react-native run-ios react-native run-android Opening issues
Verify that it is even so an issue with the latest version as specified in the previous pace. If so, open up a new issue, include the entire App.js file, specify what platforms you've tested, and the results of running this control:
If you doubtable that you've plant a spec conformance bug, then you lot can test using your component in a react-native-web project by forking this codesandbox, to meet how different browsers render the same content: https://codesandbox.io/s/pypn6mn3y7 If any evergreen browser with meaning userbase or other svg user amanuensis renders some svg content better, or supports more of the svg and related specs, please open an issue asap.
Usage
Here'southward a unproblematic case. To render output like this:
Employ the post-obit code:
import Svg , { Circle , Ellipse , G , Text , TSpan , TextPath , Path , Polygon , Polyline , Line , Rect , Use , Prototype , Symbol , Defs , LinearGradient , RadialGradient , Stop , ClipPath , Blueprint , Mask , } from 'react-native-svg' ; import React from 'react' ; import { View , StyleSheet } from 'react-native' ; export default form SvgExample extends React . Component { render ( ) { return ( < View fashion = { [ StyleSheet . absoluteFill , { alignItems: 'center' , justifyContent: 'center' } , ] } > < Svg top = "50%" width = "50%" viewBox = "0 0 100 100" > < Circle cx = "l" cy = "50" r = "45" stroke = "blue" strokeWidth = "2.5" fill = "green" / > < Rect 10 = "xv" y = "15" width = "70" elevation = "lxx" stroke = "cherry" strokeWidth = "ii" fill up = "yellow" / > < / Svg > < / View > ) ; } } Endeavour this on Snack

Supported elements:
Svg
< Svg elevation = "100" width = "100" > < Rect 10 = "0" y = "0" width = "100" height = "100" fill = "blackness" / > < Circle cx = "50" cy = "50" r = "xxx" make full = "yellowish" / > < Circle cx = "twoscore" cy = "twoscore" r = "4" fill = "black" / > < Circle cx = "threescore" cy = "twoscore" r = "iv" fill = "black" / > < Path d = "M 40 lx A 10 ten 0 0 0 60 60" stroke = "blackness" / > < / Svg >
Colors fix in the Svg element are inherited past its children:
< Svg width = "130" top = "130" fill = "blue" stroke = "red" color = "green" viewBox = "-sixteen -16 544 544" > < Path d = "M318.37,85.45L422.53,190.11,158.89,455,54.79,350.38ZM501.56,60.2L455.11,thirteen.53a45.93,45.93,0,0,0-65.11,0L345.51,58.24,449.66,162.9l51.9-52.15A35.8,35.eight,0,0,0,501.56,threescore.2ZM0.29,497.49a11.88,11.88,0,0,0,14.34,14.17l116.06-28.28L26.59,378.72Z" strokeWidth = "32" / > < Path d = "M0,0L512,512" stroke = "currentColor" strokeWidth = "32" / > < / Svg > 
Code caption:
- The fill prop defines the color inside the object.
- The stroke prop defines the color of the line fatigued around the object.
- The color prop is a flake special in the sense that it won't color anything past itself, but define a kind of colour variable that tin can be used past children elements. In this example we're defining a "greenish" color in the Svg element and using it in the second Path chemical element via stroke="currentColor". The "currentColor" is what refers to that "green" value, and information technology tin can be used in other props that take colors too, e.chiliad. fill="currentColor".
Rect
The element is used to create a rectangle and variations of a rectangle shape:
< Svg width = "200" top = "lx" > < Rect ten = "25" y = "5" width = "150" meridian = "fifty" fill = "rgb(0,0,255)" strokeWidth = "three" stroke = "rgb(0,0,0)" / > < / Svg >
Lawmaking caption:
- The width and meridian props of the chemical element ascertain the height and the width of the rectangle.
- The x prop defines the left position of the rectangle (eastward.thou. x="25" places the rectangle 25 px from the left margin).
- The y prop defines the top position of the rectangle (e.g. y="v" places the rectangle 5 px from the summit margin).
Circle
The element is used to create a circle:
< Svg height = "100" width = "100" > < Circumvolve cx = "50" cy = "50" r = "50" fill = "pinkish" / > < / Svg >
Code explanation:
- The cx and cy props define the x and y coordinates of the middle of the circle. If cx and cy are omitted, the circle's eye is set to (0,0)
- The r prop defines the radius of the circle
Ellipse
The element is used to create an ellipse.
An ellipse is closely related to a circle. The divergence is that an ellipse has an x and a y radius that differs from each other, while a circle has equal 10 and y radius.
< Svg height = "100" width = "110" > < Ellipse cx = "55" cy = "55" rx = "fifty" ry = "30" stroke = "regal" strokeWidth = "2" fill = "yellow" / > < / Svg > 
Code caption:
- The cx prop defines the x coordinate of the heart of the ellipse
- The cy prop defines the y coordinate of the center of the ellipse
- The rx prop defines the horizontal radius
- The ry prop defines the vertical radius
Line
The element is an SVG bones shape, used to create a line connecting two points.
< Svg peak = "100" width = "100" > < Line x1 = "0" y1 = "0" x2 = "100" y2 = "100" stroke = "red" strokeWidth = "2" / > < / Svg >
Code explanation:
- The x1 prop defines the offset of the line on the ten-axis.
- The y1 prop defines the kickoff of the line on the y-axis.
- The x2 prop defines the end of the line on the x-axis.
- The y2 prop defines the terminate of the line on the y-axis.
Polygon
The element is used to create a graphic that contains at least iii sides. Polygons are made of direct lines, and the shape is "airtight" (all the lines connect up).
< Svg height = "100" width = "100" > < Polygon points = "forty,5 seventy,80 25,95" make full = "lime" stroke = "purple" strokeWidth = "1" / > < / Svg >
Lawmaking explanation:
- The points prop defines the x and y coordinates for each corner of the polygon
Polyline
The element is used to create whatever shape that consists of but direct lines:
< Svg height = "100" width = "100" > < Polyline points = "10,ten 20,12 xxx,20 twoscore,60 lx,70 95,ninety" fill = "none" stroke = "black" strokeWidth = "iii" / > < / Svg >
Code explanation:
- The points prop defines the x and y coordinates for each point of the polyline
Path
The element is used to define a path.
The following commands are available for path information:
- M = moveto
- 50 = lineto
- H = horizontal lineto
- 5 = vertical lineto
- C = curveto
- S = polish curveto
- Q = quadratic Bézier curve
- T = smooth quadratic Bézier curveto
- A = elliptical Arc
- Z = closepath
Notation: All of the commands above tin can too be expressed with lower letters. Capital letter letters means admittedly positioned, lower cases means relatively positioned. See Path document of SVG to know parameters for each command.
< Svg height = "100" width = "100" > < Path d = "M25 10 L98 65 L70 25 L16 77 L11 30 L0 four L90 fifty L50 10 L11 22 L77 95 L20 25" make full = "none" stroke = "red" / > < / Svg > 
Text
The chemical element is used to define text.
< Svg height = "lx" width = "200" > < Text fill = "none" stroke = "purple" fontSize = "20" fontWeight = "bold" x = "100" y = "20" textAnchor = "heart" > STROKED TEXT < / Text > < / Svg >
TSpan
The element is used to draw multiple lines of text in SVG. Rather than having to position each line of text absolutely, the element makes it possible to position a line of text relatively to the previous line of text.
< Svg peak = "160" width = "200" > < Text y = "20" dx = "5 5" > < TSpan x = "ten" >tspan line one< / TSpan > < TSpan x = "x" dy = "fifteen" > tspan line 2 < / TSpan > < TSpan 10 = "10" dx = "ten" dy = "15" > tspan line 3 < / TSpan > < / Text > < Text x = "10" y = "60" make full = "red" fontSize = "fourteen" > < TSpan dy = "5 10 20" >12345< / TSpan > < TSpan fill = "blue" dy = "fifteen" dx = "0 5 v" > < TSpan >vi< / TSpan > < TSpan >vii< / TSpan > < / TSpan > < TSpan dx = "0 10 20" dy = "0 20" fontWeight = "bold" fontSize = "12" > 89a < / TSpan > < / Text > < Text y = "140" dx = "0 5 5" dy = "0 -5 -five" > delta on text < / Text > < / Svg > 
TextPath
In add-on to text fatigued in a direct line, SVG too includes the ability to identify text along the shape of a element. To specify that a block of text is to be rendered along the shape of a , include the given text within a element which includes an href aspect with a reference to a element.
< Svg acme = "100" width = "200" > < Defs > < Path id = "path" d = { path } / > < / Defs > < G y = "twenty" > < Text fill = "bluish" > < TextPath href = "#path" startOffset = "-10%" > We go upwardly and down, < TSpan fill up = "cerise" dy = "five,five,5" > and then up again < / TSpan > < / TextPath > < / Text > < Path d = { path } make full = "none" stroke = "red" strokeWidth = "one" / > < / G > < / Svg > 
K
The chemical element is a container used to group other SVG elements. Transformations applied to the g element are performed on all of its child elements, and whatever of its props are inherited by its kid elements. It can as well group multiple elements to be referenced later with the <Use /> element.
< Svg elevation = "100" width = "200" > < K rotation = "l" origin = "100, 50" > < Line x1 = "60" y1 = "10" x2 = "140" y2 = "ten" stroke = "#060" / > < Rect x = "60" y = "xx" height = "50" width = "80" stroke = "#060" fill = "#060" / > < Text x = "100" y = "75" stroke = "#600" make full = "#600" textAnchor = "middle" > Text grouped with shapes < / Text > < / K > < / Svg >
Use
The chemical element tin reuse an SVG shape from elsewhere in the SVG certificate, including elements and elements. The reused shape can be defined inside the <Defs> element (which makes the shape invisible until used) or outside.
< Svg summit = "100" width = "300" > < Defs > < Thousand id = "shape" > < G > < Circle cx = "50" cy = "50" r = "50" / > < Rect x = "50" y = "50" width = "l" height = "50" / > < Circle cx = "50" cy = "50" r = "5" fill = "bluish" / > < / G > < / Chiliad > < / Defs > < Use href = "#shape" x = "xx" y = "0" / > < Apply href = "#shape" x = "170" y = "0" / > < / Svg > This example shows a chemical element defined inside a <Defs> element. This makes the invisible unless referenced by a element.
Earlier the element can be referenced, it must have an ID set up on it via its id prop. The element references the element via its href prop. Notice the # in front of the ID in the prop value.
The element specifies where to show the reused shapes via its x and y props. Find that the shapes inside the element are located at 0,0. That is washed considering their position is added to the position specified in the element.
Symbol
The SVG element is used to define reusable symbols. The shapes nested inside a are non displayed unless referenced past a element.
< Svg height = "150" width = "110" > < Symbol id = "symbol" viewBox = "0 0 150 110" width = "100" meridian = "50" > < Circumvolve cx = "50" cy = "fifty" r = "forty" strokeWidth = "8" stroke = "red" fill = "red" / > < Circle cx = "90" cy = "60" r = "40" strokeWidth = "8" stroke = "light-green" fill = "white" / > < / Symbol > < Use href = "#symbol" x = "0" y = "0" / > < Apply href = "#symbol" x = "0" y = "l" width = "75" summit = "38" / > < Utilise href = "#symbol" 10 = "0" y = "100" width = "50" top = "25" / > < / Svg > 
Defs
The element is used to embed definitions that can be reused inside an SVG image. For case, you can group SVG shapes together and reuse them as a single shape.
Image
The chemical element allows a raster image to exist included in an Svg component.
< Svg height = "100" width = "100" > < Defs > < ClipPath id = "clip" > < Circle cx = "50%" cy = "50%" r = "40%" / > < / ClipPath > < / Defs > < Rect x = "0" y = "0" width = "100%" height = "100%" fill = "red" / > < Rect x = "5%" y = "five%" width = "fifty%" height = "90%" / > < Prototype x = "v%" y = "5%" width = "l%" summit = "90%" preserveAspectRatio = "xMidYMid slice" opacity = "0.five" href = { require ( '../image.jpg' ) } clipPath = "url(#clip)" / > < Text ten = "50" y = "50" textAnchor = "heart" fontWeight = "assuming" fontSize = "16" make full = "blueish" > HOGWARTS < / Text > < / Svg > 
ClipPath
The SVG element defines a clipping path. A clipping path is used/referenced using the clipPath property

The element is used to define a linear gradient. The element must be nested within a <Defs> tag. The <Defs> tag is short for definitions and contains definition of special elements (such as gradients).
Linear gradients can be defined every bit horizontal, vertical or athwart gradients:
- Horizontal gradients are created when y1 and y2 are equal and x1 and x2 differ
- Vertical gradients are created when x1 and x2 are equal and y1 and y2 differ
- Angular gradients are created when x1 and x2 differ and y1 and y2 differ
< Svg top = "150" width = "300" > < Defs > < LinearGradient id = "grad" x1 = "0" y1 = "0" x2 = "1" y2 = "0" > < Stop starting time = "0" stopColor = "#FFD080" stopOpacity = "ane" / > < Stop offset = "ane" stopColor = "red" stopOpacity = "ane" / > < / LinearGradient > < / Defs > < Ellipse cx = "150" cy = "75" rx = "85" ry = "55" make full = "url(#grad)" / > < / Svg > Code explanation:
- The id prop of the tag defines a unique proper noun for the gradient
- The x1, x2, y1,y2 props of the tag define the commencement and finish position of the gradient
- The colour range for a gradient can be composed of 2 or more colors. Each color is specified with a tag. The get-go prop is used to define where the slope color brainstorm and end
- The fill prop links the ellipse element to the gradient
Detect: LinearGradient also supports pct as prop:
< LinearGradient id = "grad" x1 = "0%" y1 = "0%" x2 = "100%" y2 = "0%" > < Finish showtime = "0%" stopColor = "rgb(255,255,0)" stopOpacity = "0" / > < End offset = "100%" stopColor = "red" stopOpacity = "ane" / > < / LinearGradient >
This result is aforementioned as the example before. But it's recommend to use exact number instead; information technology has performance advantages over using percentages.
RadialGradient
The element is used to define a radial gradient. The element must be nested within a <Defs> tag. The <Defs> tag is brusque for definitions and contains definition of special elements (such equally gradients).
< Svg height = "150" width = "300" > < Defs > < RadialGradient id = "grad" cx = "150" cy = "75" rx = "85" ry = "55" fx = "150" fy = "75" gradientUnits = "userSpaceOnUse" > < Terminate commencement = "0" stopColor = "#ff0" stopOpacity = "ane" / > < Stop offset = "1" stopColor = "#83a" stopOpacity = "ane" / > < / RadialGradient > < / Defs > < Ellipse cx = "150" cy = "75" rx = "85" ry = "55" fill = "url(#grad)" / > < / Svg > Lawmaking explanation:
- The id prop of the tag defines a unique proper name for the gradient
- The cx, cy and r props ascertain the outermost circle and the fx and fy define the innermost circle
- The colour range for a slope can be composed of two or more than colors. Each color is specified with a tag. The offset prop is used to define where the slope color begin and end
- The make full prop links the ellipse element to the gradient
Mask
In SVG, you can specify that whatsoever other graphics object or 'G' chemical element tin can be used equally an alpha mask for compositing the current object into the background.
A mask is defined with a 'Mask' element. A mask is used/referenced using the 'mask' property.
A 'Mask' can incorporate any graphical elements or container elements such as a 'G'.
The chemical element must exist nested within a <Defs> tag. The <Defs> tag is curt for definitions and contains definition of special elements (such as gradients).

v10 adds experimental support for using masks together with native elements. If you had native elements inside whatever Svg root before (which was unsupported), Then your content might change appearance when upgrading, equally due east.chiliad. transforms and masks now accept consequence.
Pattern
A pattern is used to fill or stroke an object using a pre-defined graphic object which can be replicated ("tiled") at fixed intervals in x and y to cover the areas to be painted. Patterns are defined using a 'design' chemical element and and then referenced by properties 'fill up' and 'stroke' on a given graphics chemical element to indicate that the given element shall exist filled or stroked with the referenced pattern. The element must exist nested within a <Defs> tag. The <Defs> tag is short for definitions and contains definition of special elements (such as gradients).

Marker
A marker is a symbol which is attached to one or more vertices of 'path', 'line', 'polyline' and 'polygon' elements. Typically, markers are used to make arrowheads or polymarkers. Arrowheads can be defined by attaching a marking to the offset or cease vertices of 'path', 'line' or 'polyline' elements. Polymarkers tin be divers by attaching a marker to all vertices of a 'path', 'line', 'polyline' or 'polygon' element.
The graphics for a marker are defined past a 'marker' element. To signal that a particular 'marker' element should be rendered at the vertices of a particular 'path', 'line', 'polyline' or 'polygon' element, set up i or more than marker properties ('marker', 'marker-start', 'marking-mid' or 'marker-cease') to reference the given 'mark' element.

ForeignObject
SVG is designed to be compatible with other XML languages for describing and rendering other types of content. The 'foreignObject' element allows for inclusion of elements in a non-SVG namespace which is rendered within a region of the SVG graphic using other user agent processes. The included foreign graphical content is subject to SVG transformations, filters, clipping, masking and compositing.
One goal for SVG is to provide a mechanism past which other XML language processors tin can render into an area within an SVG cartoon, with those renderings subject to the various transformations and compositing parameters that are currently agile at a given bespeak inside the SVG content tree. 1 particular case of this is to provide a frame for XML content styled with CSS or XSL and then that dynamically reflowing text (subject to SVG transformations and compositing) could be inserted into the middle of some SVG content.

Bear upon Events
Affect events are supported in react-native-svg. These include:
-
disabled -
onPress -
onPressIn -
onPressOut -
onLongPress -
delayPressIn -
delayPressOut -
delayLongPress
You tin can use these events to provide interactivity to your react-native-svg components.
< Circumvolve cx = "50%" cy = "50%" r = "38%" make full = "red" onPress = { ( ) => alert ( 'Press on Circle' ) } / >
