[pigeon] Add support for collections of enums #133728
Description
Activity
Hello,
Any news for this issue
I guess it's still not working.
However, I figured out the following workaround by wrapping enum to the class, so it's a bit better type-safety than
List<int?>(collection of ordinals) orList<String?>(collection of enum names):let's say we have following enum:
enum Pet{CAT, DOG, FISH; }
instead of
@FlutterApi() abstract class PetsApi { List<Pet?> getPets(); }
do the following:
class PetResponse{ Pet? pet; //Pet.CAT String? key; //"cat" }
The flutter api would look the following(you can map/filter nulls on native side)
@FlutterApi() abstract class PetsApi { List<PetResponse?> getPets(); }

As of flutter/packages#4580 pigeon supports enums as primitives across all platforms.
It still does not support collections of enums though.
List<Enum>is a fairly common type even in our own packages (ie. local_auth_ios), as such should be supported by pigeon.Map<Enum>would is also needed.
