Rive animation crashes Android x86 emulator

[antonio-arbo]

Description

Animations in Flutter Rive causes the Android x86 emulator to crash. Some animations work for a very short period of time, but then it causes the entire emulator to crash with SIGSEGV / error 139.

I reproduced this 100% of the times with multiple versions of the emulator and system images. Easiest is to use your own sample app, but I first found this in our own app.

Steps To Reproduce

Steps to reproduce the behavior:

1. Spin up a docker emulator using https://source.android.com/docs/devices/automotive/start/avd/cloud_emulator
2. Download Flutter Rive sample from https://github.com/rive-app/rive-flutter/tree/master/example
3. flutter pub get && flutter run -d sdk
4. click on some animation to render; you may need to go back and then click again once or twice but it will crash in seconds.

From sample Flutter Rive.

TLDR: use -gpu swangle (worked for me) or -gpu host if nvidia GPU is available.
