Check Internet Connection Like a SENIOR in Flutter - Globally 

@override void onInit() { super.onInit(); _checkInitialConnectionStatus(); _connectivity.onConnectivityChanged.listen(_updateConnectionStatus); } void _checkInitialConnectionStatus() async { ConnectivityResult connectivityResult = await _connectivity.checkConnectivity(); _updateConnectionStatus(connectivityResult); } modify your NetworkController class like this and instead of calling the DependencyInjection.init(); inside the main function use it inside the initState of the child of the runApp();

got the same error...you found any solution bro?

Yes you can , please make it so I will merge it

why this error "The argument type 'void Function(ConnectivityResult)' can't be assigned to the parameter type 'void Function(List)?'"

@@MrAmrmnabil74 i think one parameter is missing

@@adityaaggarwal0 does this code worked with you ?

@@MrAmrmnabil74 yes it works, but sometimes its buggy. Will find better solution later but works for now

Noted

Thank you

Yes, it is in our plan.

Yes, if you build your app based on Getx, it is very wrong, but in some cases it is not a problem to use it.

​@@flutterguyscan you tell us why ?

@@iigama_yt3016 actually, getx it self has many bugs

Usually, in applications, when the user is not connected to the Internet and opens the application, we check separately on the splash page and give a warning.

Yes, you can

You can use global navigator key. And inside bloc constructor, start listening to connectivity stream. As connectivity change, show snack bar or toast and use context of global navigator key. Use google to find how to use global navigator key.

@@flutterguys thanks 👍

I think you can't handle it , But please check Snackbar properties.

I have to fix it but I don't have time unfortunately. If you can fix it, and make a merge request on GitHub and I will merge.

@@flutterguys Hahaha, I mean, I'm a beginner and I'm confused to fix it.

I don't know if you still need this but here is the solution anyways lol. the logic to show the snackbar when the device goes offline, but it likely won't trigger if the initial state is offline because the listener in _updateConnectionStatus starts listening after initialization. replace oninit() methode in the networkcontroller with this methode and that should do it: void onInit() { super.onInit(); _connectivity.checkConnectivity().then((result) { _updateConnectionStatus(result); }); _connectivity.onConnectivityChanged.listen(_updateConnectionStatus); }

@@fadij.8760 thanks bro ❤

Soon

Please check source code

@@flutterguys I went through all your code and used it exactly. The situation I said is not resolved. Solved when using internet connection checker instead of Connectivity Plus.

Yes

How can I give some idea hints to implement that ??​@@flutterguys

Yes

You need use GetMaterialApp insted of MaterialApp

@@flutterguys I have use the same code you do ditto copy but still when I use screen on main as you do then also snack bar not showing at all

@@flutterguys done actually network injection file was inside controllers folder tahtswhy not showing

Yes

Thank you for your support ❤ Yes you can use other state managements like Bloc or Riverpod ... getx is really useful, but on the condition that you only use it in certain situations, like in this video. And it is better to use bloc or riverpod to manage the state.

You should modify it like this: void _updateConnectionStatus(List connectivityResult) { if (connectivityResult.contains(ConnectivityResult.none)) { Get.rawSnackbar( messageText: const Text('No internet connection')...... etc
