[bigdogs]

hi,
what the difference between StateNotifierProvider and NotifierProvider? I found that their document and example demo seem extacly same....
https://docs-v2.riverpod.dev/docs/providers/notifier_provider
https://docs-v2.riverpod.dev/docs/providers/state_notifier_provider

Docuemnt said NotifierProvider is preferred.. But the constructor fuction of NotifierProvider doesn't have WidgetRef which means I can't observer other provider use NotifierProvider?

I'm really consufused :(

Ref is available in Notifier & AsyncNotifier providers by default. You don't have to pass it via the constructor.

sorry for my poor English. I mean argument of the functor to create the NotifierProvider is not a WidgetRef, then I can't watch other provider ...

StateNotifierProvider can watch other provider, but the document said it's not preferred, and didn't say why..

I have no idea which one should be used

You can use ref.watch(anyProvider) inside Notifier class (ExplorerProvider) .
