I think you need to

yarn add react-native-svg
react-native link react-native-svg

For our testing we use expo, and it comes with react-native-svg out of the box.

Adding on to @Hermanya

react-native-svg currently has a bug where automatic linking pulls in libRNSVG-tvOS.a to your Link Binary with Libraries list. Either manually add the project to Xcode, or remove libRNSVG-tvOS after running react-native link react-native-svg

See more here

Do not forget rebuild your app: react-native run-android

All working fine with example app, but while integrating to main project displaying this issues

Not Working for me, I have tried all

after link this was adding in podfile
pod 'RNSVG', :path => '../node_modules/react-native-svg'

I have installed previously linear-gradient package and installl pods for react-native-crop-image-picker

does this effects on this package?
please respond me

[Hermanya]

I don't think it does, if you could make another example project, more similar to your main project, to reproduce this issue. I could take a look.

My suspicion is that your main project might have older versions of dependencies.

I had fixed this issue by removing pods and run react-native link react-native-svg and then reinstalling the pods for iOS
for Android it works fine from before

yes, maybe that is the problem.. you could mention this in the installation guide. I had to install react-native-svg and I am using xcode
