| * override is consistent with all overridden methods from other migrated |
| * libraries in the super-interface chain, since a legacy library is permitted |
| * to override otherwise incompatible signatures for a method. |

| * @description Check that if generic opted-in class implements two classes (one |
| * is legacy) with [FutureOr<non_nullable_type>] type parameter, child opted-in |
| * class type parameter can extend non-nullable [FutureOr<non_nullable_type>] |
