I get this when attempting to generate these mocks: https://github.com/Rexios80/packages_flutter/blob/afb21bc501403de977c404c995cbc41502381d9b/packages/google_maps_flutter/google_maps_flutter_web/example/integration_test/google_maps_controller_test.dart#L24

I had this issue before switching to the latest commit of mockito (which should really be released by now): #732

This is the type that's causing the issue:

abstract class GeometryController {
  /// The GMap instance that this controller operates on.
  late gmaps.Map googleMap;
}

@JS('google.maps.Map')
extension type Map._(MVCObject _) implements MVCObject {}

I tried adding googleMap to the unsupportedMembers but it doesn't make a difference

Okay I swear I tried adding something to fallbackGenerators to fix this before but I did it just now and it works

Mockito still shouldn't crash so we'll leave this open.

I was playing around with mocks for dart:js_interop and also came across this with multiple JS interop types, making it hard to generate mocks for classes that use JS interop types. Out of curiosity, do we use the mock types from https://github.com/dart-lang/sdk/blob/91a653b4e55b5f969e02a83a2ecb8842df534040/pkg/analyzer/lib/src/test_utilities/mock_sdk.dart#L1533 for these types?

I suspect the edge case here is because dart:js_interop types have a representation type that's an internal type.
