Question 1

How do I add a retry button for network connectivity in Flutter?

Accepted Answer

Use the OfflineRetryController with OfflineBuilder, as shown in the README. Instantiate the controller, listen to changes, and trigger retry on button press with configurable exponential backoff for manual attempts.

Question 2

Flutter Offline vs connectivity_plus: which one should I use?

Accepted Answer

Flutter Offline builds on connectivity_plus to provide UI widgets and retry logic, while connectivity_plus is a lower-level package for raw connectivity data. Choose Flutter Offline for ready-made UI components; use connectivity_plus if you need basic connectivity checks without UI helpers.

Question 3

Does Flutter Offline cache data when offline?

Accepted Answer

No, it only handles connectivity status detection and UI updates. For data caching, you must implement separate solutions using packages like hive or shared_preferences, as it doesn't manage offline data persistence.

Question 4

How to test an app using Flutter Offline?

Accepted Answer

Run 'flutter test' as mentioned in the README. You can mock connectivity states in widget tests by simulating ConnectivityResult changes, but the package itself doesn't provide extensive testing utilities beyond standard Flutter tools.

Question 5

Can I use Flutter Offline with the Provider package?

Accepted Answer

Yes, since it's based on ChangeNotifier, it can be integrated with Provider for state management. However, you might need to wrap it in a Provider context or use additional listeners for complex setups.

Question 6

What permissions does Flutter Offline need for Android?

Accepted Answer

It requires the INTERNET permission to be added manually to the Android manifest, as specified in the README. This is necessary for connectivity detection but can be a source of errors if forgotten.
