I'm working on a Flutter app for Android, and I'm getting the following error in the logs:

E/BLASTBufferQueue( 7630): [SurfaceView[com.example.flutter/com.example.flutter.MainActivity]#9](f:1,a:4) acquireNextBufferLocked: Can't acquire next buffer. Already acquired max frames 4 max:2 + 2

Context:

I'm using Flutter 3.27.1 on VSCode.
The app uses native Android code (XML UI) and integrates with Flutter.
The app is for field-level medical representatives to order medicine and includes dashboards and analytics.
I have custom UI components and some animations in the app.

What I've Tried:

Reducing UI rebuilds by using const widgets where possible.
Running flutter clean and rebuilding the app.
Ensuring debugRepaintRainbowEnabled = false.
Checking for heavy widgets and optimizing lists with ListView.builder.
Setting android:hardwareAccelerated="true" and android:largeHeap="true" in AndroidManifest.xml.

Questions:

What exactly causes this error, and how can I fix it effectively?
Is there a way to manage or increase buffer limits for Flutter's SurfaceView?
Would limiting the frame rate or optimizing native code help, and if so, how can I do that?

the same applies to me : following the last update (AS and Flutter) this error appeared. May be due to the InteractiveViewer widget, but don't know why.

However this message does not prevent the code from working properly
