Immutable bloc state versus mutable ChangeNotifier
WHAT IT TESTS: reasoning about state mutability trade-offs. OUTLINE: immutable gives predictable diffs, easy debugging and replayability at the cost of boilerplate; mutable is terse but error-prone. RED FLAG: declaring one universally superior with no nuance.
WHAT IT TESTS: whether you can weigh predictability against pragmatism in state design. ANSWER OUTLINE: immutable states with bloc plus freezed produce new objects per change, giving clear equality, time-travel debugging, safe sharing and easy testing, but cost copyWith boilerplate and code generation. ChangeNotifier mutates in place and calls notifyListeners, which is terse and fast for small UIs but risks missed notifications, accidental shared mutation, and harder reasoning.
