CC @stereotype441 – trying out your fix for generic function types...

[kevmoo]

Reproducing with the original example from - #33159

class Config {
  final int value;
  Config(this.value);
}

Config fromJson(Map json) =>
    checkMethod(json, (check) => new Config(check('value', (v) => v as int)));

typedef _CheckedConvert = S Function<S>(String key, _CastFunction<S>);

typedef _CastFunction<R> = R Function(Object);

T checkMethod<T>(
  Map map,
  T constructor(_CheckedConvert converter),
) {
  Q _checkedConvert<Q>(String key, _CastFunction<Q> castFunc) {
    return castFunc(map[key]);
  }

  return constructor(_checkedConvert);
}
