Flutter State Smackdown: Comparing BLoC, Provider, Riverpod
summary
A small water‑tracker app is built and run with three state systems side‑by‑side: a counter that changes in +400 ml increments and shows current ML versus goal across grid/gallery/board views. Provider is implemented with ChangeNotifier and hits unwanted rebuilds and spaghetti state for larger screens. BLoC uses explicit events and emits states for predictable behavior and scales to enterprise. Riverpod uses StateNotifier, autoDispose and compile‑time safety; forget to dispose streams and overwrapping providers still leaks.
