When opening Show Graphics HUD Develop tools (Setting->Developer->Show Graphics HUB)

@cj3479 Where are you doing this change ? Can you upgrade to latest master and re-run your scenario to check if the crash still persists or not ?

Yes I use latest master , It still crashes, I suspect that Flutter might be incompatible with Unity or Unreal when enable the graphics debugging switch

The Flutter app that do not embed into Unity or Unreal do not have this issue

gaaclarke commented 2 months ago
  1. Is this on device or simulator?
  2. How are you embedding flutter into unity?

It may be the case that you have improper synchronization between unity's renderer and flutter's renderer.

@cj3479 Similar to https://github.com/flutter/flutter/issues/150929#issuecomment-2224715020, it would be helpful if you could provide a complete sample code so that we can look into it easily. Thanks!

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now. If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones. Thanks for your contribution.
