flame_3d RSS Memory Leak when targeting Pixel 7 Pro

まず、物理的な Pixel 7 Pro で flutter run を使って flame_3d の例を実行し、debug、profile、release モード全体で Flutter DevTools の RSS を監視します。報告されたスタックフレーム InternalFlutterGpu_RenderPass_Begin を調査の初期ポイントとして使用します。例が RSS の継続的な増加や out-of-memory クラッシュなしに実行されれば完了です。

What happened?

The flame_3d example (and anything I would make using flame_3d) runs for ~1 minute and then crashes due to an out of memory error. The memory tab in Flutter DevTools shows RSS memory increasing consistently over time, even if I don't interact with the app at all. Running in different modes (release vs. debug vs. profile) changes nothing.

What do you expect?

No out of memory error

How can we reproduce this?

Do flutter run on the flame_3d example (or anything that uses flame_3d) and targeting a (physical, not emulated) Google Pixel 7 pro.

What steps should take to fix this?

No response

Do have an example of where the bug occurs?

The flame_3d example (or any code using flame_3d)

Other information

I don't have any other physical Android devices to test with. I'm not sure if it's just my phone that's the problem; although, if it is, I would be grateful for advice to fix it.
