Direzione di ricerca

Inizia eseguendo l’esempio flame_3d con flutter run su un Pixel 7 Pro fisico e monitora RSS in Flutter DevTools nelle modalità debug, profile e release. Usa lo stack frame InternalFlutterGpu_RenderPass_Begin riportato come punto iniziale dell’indagine; il lavoro è completato quando l’esempio viene eseguito senza un aumento continuo di RSS o un crash per esaurimento della memoria.

Scritto dal modello di indicizzazione a partire dal testo della issue.

Descrizione

bug
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.
