The error with flutter viewport, when I try to run the app on android, even on chrome. I tried the following:

  • re-installing flutter
  • creating new projects
  • cloning an existing projects
  • run on web update android studio
  • user different versions of Gradle
  • upgrading java
  • flutter pub cache clean
  • removing the build folder

the exception:

/flutter/packages/flutter/lib/src/rendering/viewport.dart:1375:15: Error: Expected an identifier, but got '.'.
Try inserting an identifier before '.'.
              .hasthrow FlutterError.fromParts(<DiagnosticsNode>[
              ^
/flutter/packages/flutter/lib/src/rendering/viewport.dart:1375:16: Error: Expected ';' after this.
              .hasthrow FlutterError.fromParts(<DiagnosticsNode>[
               ^^^^^^^^
