Description

Description

I am using the latest rive prerelease 0.14.0-dev.8 and I am experiencing a rendering issue when resizing a RiveWidget on Android. When ever the animation is getting resized it disappears and reappears without throwing an error. On iOS it is working as expected. I attached a video showing the issue. If needed I can provide a reproducible repo and the riv file in a private message.

Expected behavior

Should be showing the Rive animation without disappearing.

Research direction

Start by reproducing the resize behavior in a RiveWidget on Android using Flutter 3.35.4 and Rive prerelease 0.14.0-dev.8, testing both an emulator and a physical device if available. Compare the behavior with iOS and verify that the animation remains visible throughout resizing without errors.
