We’ve released a hotfix to Flutter which moves the latest stable to 2.0.5. This fixes a Dart compiler crash when compiling your application first described in #79949 and #80509. #43506 (dart-lang/sdk) describes the root cause of the issue for those who are curious.
This fix has landed in all channels. We recommend that you upgrade Flutter by running flutter upgrade.
