This exception is thrown when calling TypeChecker.isAssignableFromType(type) when type is dynamic or has dynamic type parameters.

For example:

final dynamic field1;
final Map field2;
final Set<dynamic> field3;

Here are my type checkers:

  /// [TypeChecker] for [Map].
  final mapChecker =
      const TypeChecker.typeNamed(Map, inPackage: 'core', inSdk: true);

  /// [TypeChecker] for [Set].
  final setChecker =
      const TypeChecker.typeNamed(Set, inPackage: 'core', inSdk: true);

  /// [TypeChecker] for [Iterable].
  final iterableChecker =
      const TypeChecker.typeNamed(Iterable, inPackage: 'core', inSdk: true);

Sorry about that!

I think it's already fixed in 9388e3c

Let's do a release.

Released as 4.0.2, please re-open if that doesn't fix the issue. And, thanks for reporting :)
