Please help me out.

@itsusmanmirza are you running example in this repo ?

[UsmanTechJive]

No not in this repo I'm importing this in my own project, in Home Screen.tsx, and yes I'm using TypeScript as well.

[codesinghanoop]

are you already having react-native-svg version in your project before integrating this library ? @itsusmanmirza

[UsmanTechJive]

Yes react-native-svg was already installed and I'm using this version.

[codesinghanoop]
