N/A
No issues found!
App was built on CI, some time ago, so I could not execute shell commands. However, here is the relevant part of the log which is available:
Flutter 2.8.1 • channel unknown • unknown source
Framework • revision 77d935af4d (3 months ago) • 2021-12-16 08:37:33 -0800
Engine • revision 890a5fca2e
Tools • Dart 2.15.1
It looks like there is an issue with code here: https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/widgets/router.dart#L666
static final Future<dynamic> _never = Completer<dynamic>().future; // won't ever complete
_AsyncPassthrough<T> _verifyRouteInformationParserStillCurrent(Object? transaction, Router<T> originalWidget) {
return (T data) {
//...
return _never as Future<T>;
};
}
dynamic is not an Object
