how to make firestore data online only?-CodePudding

I want to make the user to access firestore data in my flutter app only when they are online. hope for positive response...ignore my poor English.

I am expecting that firestore data can't stored in cache memory. user only get the data when they are online.

CodePudding user response：

you can check the internet by using connectivity_plus: ^3.0.2 package and with this package u can apply ur logic regarding connectivity...

CodePudding user response：

you can check the internet by using connectivity_plus: ^3.0.2 package so you can disable delete button if there is no internet

Your code will be like this:

YourAppState{
    ConnectivityResult _connectionStatus = ConnectivityResult.none;
    final Connectivity _connectivity = Connectivity();
    late StreamSubscription<ConnectivityResult> _connectivitySubscription;

  @override
   void initState() {
   super.initState();
   _connectivitySubscription_connectivity.onConnectivityChanged.listen(_updateConnectionStatus);
  }

   Future<void> _updateConnectionStatus(ConnectivityResult result) async {
     setState(() {
       _connectionStatus = result;
     });
      if (_connectionStatus.toString() == "ConnectivityResult.none") {
         navigatorKey.currentState!.popUntil((route) => route.isFirst);
        }
    }

}

Then up your widget write this condition

if(_connectionStatus.toString() != "ConnectivityResult.none")

now if there is no internet connection the widget will not appear

It sounds like your question is just asking how to disable any persistence to confirm that your app is only receiving up-to-date data. You can configure that with your Firebase settings. Below is a snippet of code from the documentation.

// Apple and Android
db.settings = const Settings(persistenceEnabled: true);

// Web
await db
    .enablePersistence(const PersistenceSettings(synchronizeTabs: true));
