dispose method

@override Future<void> dispose()

Balances one initialize call. Monitoring stops, and an inactive state is emitted, only when the last caller disposes.

Implementation

@override
Future<void> dispose() => _serialized(() async {
      if (_refCount == 0) return;
      _refCount--;
      if (_refCount > 0) return;
      final subscription = _eventSubscription;
      _eventSubscription = null;
      await subscription?.cancel();
      _emit(const CallState.initial());
      await methodChannel.invokeMethod<void>('dispose');
    });
