[pigeon] nonnull enums are broken #100594
Description
Nonnull enums are broken now even with a wrapper class. Switching the enum to a nullable in the class fixes it.
Steps to Reproduce
Interface:
enum MyState {
Idle,
}
class MyWrapper {
late MyState state;
}
@FlutterApi
abstract class MyApi {
void setState(MyWrapper state);
}
Error:
30: pigeonMap['state'] = state == null ? null : state!.index; (warning) The '!' will have no effect because the receiver can't be null.
#unnecessary_non_null_assertion
39: state: pigeonMap['state'] != null The argument type 'MyState?' can't be assigned to the parameter type
'MyState'. #argument_type_not_assignable
