ART

This library has been removed as of SDK 36. You likely want to use Svg which is more feature complete, has better documentation, and is a more standard implementation of vector graphics.
If you need to use react-native-progress, which relies on ART, you can use the bare workflow and install @react-native-community/art, or implement your own progress indicator using Svg (here's an example).
Again, you almost definitely want to use Svg instead of this unless you are really sure you want to use ART for some reason.
