Migration: 0.13.x → 0.14.x

• In 0.14.0 the way StateNotifierProvider and state/notifier reading work changed.

Changes#

1. StateNotifierProvider gets an extra type parameter: the state type.

   • Before: StateNotifierProvider<MyStateNotifier>(...)
   • After: StateNotifierProvider<MyStateNotifier, MyModel>(...)

2. Reading the notifier

   • Before: watch(provider) returned the StateNotifier.
   • After: use provider.notifier: watch(provider.notifier) to get the StateNotifier.

3. Reading the state

   • Before: watch(provider.state) for the state.
   • After: watch(provider) returns the state directly.

CLI migration#

• Install: dart pub global activate riverpod_cli
• In the project (do not upgrade Riverpod first): run riverpod migrate.
• The tool will suggest edits (e.g. watch(provider.state) → watch(provider)). Accept with y or reject with n.
