can you try to call same function within onReady() ? Can you specify getx version you are using?

My get version is 4.6.1 , Anyways that error automatically resolves in my project.. Idk how but it is working now.. 😅
@Shreemanarjun get 4.6.5 and I changed getx version to 4.6.1 issue fixed.
When run the get.back() method, it gives an error, the following snackbar controller is not initalized, I am not using the snackbar anyway. Sometimes when I come back from the screen, it gives this error, sometimes when closing the dialogs.
Same, getting this error using Get.back(). Using 4.6.5 and downgraded to 4.6.1 and still getting this. This is an old-ish ticket with only a handful people getting it, must be something we're doing wrong on our ends.
@jonex41 Check it please I was getting the same error I found what was causing it and realized that I am trying to call the Snackbar without GetMaterialApp loaded.
For example:
void main(){
// Let this be our method that runs the snackbar
checkInternetConnection();
runApp(App());
}
///
void checkInternetConnection(){
if(status){
// Show Snackbar
}else{
// Show Snackbar
}
}
/**
* When you use it this way, Snackbar will not work and will crash.
* It will also cause the `Get.back()` method to crash.
*/
class App extends StatelessWidget{
@override
Widget build(BuildContext context){
return GetMaterialApp(...)
}
}
@taylanyildiz i am using the getmaterialApp(), my issues is that i have it working fine when i open my app on tapping on icon, but when i terminate app and open from notification, that when i get the issues, the Get.back dont work, the snackbar is not showing, all of those
