How to listen to partial state changes (i.e. select) without hooks?

[wujek-srujek]

I'm using Riverpod with StateNotifier in a Flutter app without hooks. The state managed by the notifier contains a few
fields, and in some cases I just want to react to changes to only a part of the state.

enum TimerStatus {
  running,
  paused,
  // Stopped preemptively by the user.
  stopped,
  // Stopped naturally, i.e. it run to the end.
  completed,
}

@immutable
class TimerState {
  final Duration remaining;
  final TimerStatus status;

  const TimerState(
    this.remaining,
    this.status,
  );
}

The notifier and provider look like this:

class TimerNotifier extends StateNotifier<TimerState> {
  // ...
}

final timerNotifierProvider = StateNotifierProvider.autoDispose
    .family<TimerNotifier, TimerState, Duration>(
  (ref, interval) {
    // ...
  },
);

I tried using the select method in build using the Consumer widget:

final timerStatus = watch(
   timerNotifierProvider(widget.interval).select((value) => value.status),
);

but I can't get the code to compile with:

The argument type 'ProviderListenable<TimerStatus>' can't be assigned to the parameter type 'ProviderBase<Object?, dynamic>'.

Is this supposed to work?

Anyways, I made it work using a second provider that does the selection itself:

final timerStatusProvider =
    Provider.autoDispose.family<TimerStatus, Duration>(
  (ref, interval) => ref.watch(timerNotifierProvider(interval)).status,
);

and it works, but seems like quite some boilerplate to need to reimplement what select does. Is what I'm doing the right thing?
If select is only meant for hooks, shouldn't it be part (like an extension function or something) of hooks_riverpod to avoid confusion, like in my case?

What version of riverpod are you running? Riverpod 1.0.0-dev supports select without the need of hooks.

I'm using 0.14.0+3, 'latest' on Pub. I'm not ready to use dev (unstable?) releases - unless you tell me that this version is anyway more stable than 0.14.0+3.

1. When is it planned to have a stable 1.0.0 release?
2. Apart from upgrading, is a dedicated provider, like in my example, the right thing to do?

As soon as it is ready

Yes

I think a misunderstanding is on the way. I didn't mean to be rude or hasten things up, I was just curious about the possible time frame. A week, month, year? But if you don't know, that's also an answer. I do understand it is a project you work in your free time.
