didUpdateProvider method

@override void didUpdateProvider(ProviderObserverContext context, Object? previousValue, Object? newValue)

Called by providers when they emit a notification.

• newValue will be null if the provider threw during initialization.
• previousValue will be null if the previous build threw during initialization. mutation If the change is caused by a "mutation", [] will be the invocation that caused the state change. This includes when a mutation manually calls state=:

@riverpod
class Example extends _$Example {
  @override
  int count() => 0;

  @mutation
  int increment() {
    state++; // This will trigger `didUpdateProvider` and "mutation" will be `#increment`

    // ...
  }
}

Implementation

@override
void didUpdateProvider(
  ProviderObserverContext context,
  Object? previousValue,
  Object? newValue,
) {
  _logger.d('Provider ${context.provider.name ?? context.provider.runtimeType} updated\n'
      '  from: $previousValue\n'
      '  to: $newValue');
}
