avoid-calling-notifier-members-inside-build

added in: 1.19.0
warning
Pro+

Warns when a Notifier (or AsyncNotifier) member is called inside the build method.

Calling notifier methods in build can lead to unwanted side effects and inefficient code, as the build method can be invoked frequently.

Example​

❌ Bad:

class HomeConsumerState extends ConsumerState<HomeConsumerStatefulWidget> {
  @override
  Widget build(BuildContext context) {
    final counter = ref.watch<Counter>(provider.notifier);

    counter.increment(); // LINT: Avoid using notifier members inside the 'build' method.
  }
}

✅ Good:

class HomeConsumerState extends ConsumerState<HomeConsumerStatefulWidget> {
  @override
  Widget build(BuildContext context) {
    final counter = ref.watch<Counter>(provider.notifier);

    return Button(onTap: counter.increment);
  }
}
