Dart Error: Can't load Kernel binary: Invalid kernel binary format version.

I've done "flutter channel stable && flutter upgrade"
but still get this error when run the simple app:
[ERROR:engine/src/flutter/shell/common/shell.cc(210)] Dart Error: Can't load Kernel binary: Invalid kernel binary format version.
[ERROR:engine/src/flutter/shell/common/engine.cc(220)] Could not prepare to run the isolate.
[ERROR:engine/src/flutter/shell/common/engine.cc(159)] Engine not prepare and launch isolate.
[ERROR:engine/src/flutter/shell/common/shell.cc(491)] Could not launch engine with configuration.
flutter: Observatory listening on http://127.0.0.1:32771/uTjhwBkUzr4=/

flutter doctor shows:
Flutter (Channel stable, 1.22.3, on Mac OS X 10.15.3 19D76

Could you help on that?
do I need to config flutter or something?

I just tried to run 'flutter build bundle' to get the asset and not the release mode.

Thank you very much!

Have you made sure the asset bundle on your Raspberry Pi is up to date?
To be really certain, you can check the modification timestamp of the flutter_assets/kernel_blob.bin file on your Raspberry Pi matches the modification timestamp of the same file on your host machine. (Using stat) If they don't match, something went wrong when deploying the assets.

Thank you for your advise. The app bundle must be not updated with the latest flutter because it is an old app. after I create a new app it works well.
Closing the issue.
