The app will crash when using flare on android version 8 and 8.1 (Oreo)

[harshalrj25]

This seems to be specific to android 8 and 8.1 ie oreo

I have tried multiple examples, any flare animation after a certain time consumes a lot of memory which results in a crash.

I have checked flutter doctor, then used profiling to track memory usage.

Tested on debugging and release both modes.

The issue still persists, the only workaround is to replace a .flr file with a gif or png.

Below is log that you get after the crash.

Thanks for filing! Would you be able to share the Flare file and/or source code that shows the problem?

flaredemo-master.zip

Shared a demo repo that i downloaded,
If you build and run it on Oreo it will show two button's
Tap on the button named "Build and Fade Out" continuesly for 5-6 times this will trigger the issue.
