Extending dart freezed with deep collection copyWith.
Features #

✅ FreezedList<T>.fromJson
✅ FreezedList<T>.copyWith.replaceFirst(T newElement, bool Function(T element) what)

Example #
@freezed
class One with _$One {
const factory One(String name, Two two) = _One;

factory One.fromJson(Map<String, dynamic> json) => _$OneFromJson(json);
}

@freezed
class Two with _$Two {
const factory Two(String name, FreezedList<Three> threes) = _Two;

factory Two.fromJson(Map<String, dynamic> json) => _$TwoFromJson(json);
}

@freezed
class Three with _$Three {
const factory Three(String name) = _Three;

factory Three.fromJson(Map<String, dynamic> json) => _$ThreeFromJson(json);
}

void test() {
final var1 = One('1', Two('2', FreezedList([Three('31'), Three('32'), Three('33')])));
final var2 = One('1', Two('2', FreezedList([Three('31'), Three('32'), Three('33')])));
final var21 = var2.copyWith();
expect(var1, equals(var2));
expect(var1, equals(var21));
final var3 = var21.copyWith
.two(name: '21')
.copyWith
.two
.threes
.replaceFirst(Three('XXX'), (element) => element.name == '31');
expect(var3, isNot(var21));
final var4 = var3.copyWith
.two(name: '2')
.copyWith
.two
.threes
.replaceFirst(Three('31'), (element) => element.name == 'XXX');
expect(var4, equals(var21));
