Over here says sdk: ">=2.12.0 <3.0.0" https://github.com/thingsboard/flutter_thingsboard_app/blob/master/pubspec.yaml#L9

However, 2.12.x doesnt have any stable versions. Only beta version has 2.12.x. https://docs.flutter.dev/development/tools/sdk/releases

@jiekechoo So we need to change qr_code_scanner: ^0.6.1 to qr_code_scanner: ^1.0.0? Have you made it working? Thanks a lot.

This approach works. I can run the app on Flutter 3 now. Have some warnings during compilation btw.
