Network Status

Fasq uses NetworkStatus to intelligently pause retries when offline and resume them when online. It also manages the offline mutation queue.

[!NOTE] The core fasq package does not depend on platform-specific plugins like connectivity_plus to keep the package lightweight and pure Dart where possible. You must connect your connectivity logic to Fasq.

Usage

1. Setup Connectivity

You typically want to listen to network changes at the root of your app (e.g., in main.dart or your root widget) and update Fasq.

Using connectivity_plus example:

import 'package:connectivity_plus/connectivity_plus.dart';
import 'package:fasq/fasq.dart';
 
void main() {
  // 1. Listen to connectivity changes
  Connectivity().onConnectivityChanged.listen((List<ConnectivityResult> results) {
    // 2. Determine if online
    final isOnline = !results.contains(ConnectivityResult.none);
    
    // 3. Update Fasq
    NetworkStatus.instance.setOnline(isOnline);
  });
 
  runApp(MyApp());
}

2. What Fasq Does

Once NetworkStatus is aware of the state:

• Offline:

  • Queries will stop retrying on failure.
  • Mutations configured with queueWhenOffline: true will be added to the queue.
  • QueryState will remain in its last known state.

• Online:

  • Paused queries will immediately attempt to refetch.
  • The offline mutation queue will begin processing.

3. Manual Override (Testing)

You can manually force the status for testing purposes.

// Force offline mode to test UI
NetworkStatus.instance.setOnline(false);
 
// Force online mode
NetworkStatus.instance.setOnline(true);
