This is a very simple issue:
/// Before a test file is executed, the Flutter test framework will scan up the
/// directory hierarchy, starting from the directory in which the test file
/// resides, looking for a file named `flutter_test_config.dart`. If it finds
/// such a configuration file, the file will be assumed to have a `main` method
/// with the following signature:
///
/// ```dart
/// Future<void> main(FutureOr<void> testMain());
/// ```
This is what the flutter_test documentation says.
When I try to write the following code using Dart 2.12.0 (build 2.12.0-29.10.beta):
Future<void> main(FutureOr<void> Function() testMain) async {
await testMain();
}I receive the following error:
The type of the first positional parameter of the 'main' function must be a supertype of List.
It seems like what flutter_test used for configuration is now impossible.
