How to show snackBar without Scaffold

Question

I am trying to show snackbar in my app to notify User but without scaffold it shows me error. My current code is:

scaffoldKey.currentState?.showSnackBar(
           


        

Answer 1

No, It is not possible. Snackbar is part of Scaffold. It must have a Scaffold parent. Snackbar

Inside Scaffold parent, you can do like below

BuildContext con=context;
final snackBar = SnackBar(content: Text(message));
Scaffold.of(con).showSnackBar(snackBar);

Answer 2

It can get the current context and show snackbar like this:

void _showToast(BuildContext context) {
  final scaffold = Scaffold.of(context);
  scaffold.showSnackBar(
    SnackBar(
      content: const Text('Updating..'),
    ),
  );

this._showToast(context);

Answer 3

Use https://pub.dev/packages/get

then you can simply call the Get.snackbar() to show the snackbar where you want it to be displayed.

Get.snackbar('Hi', 'i am a modern snackbar');

NOTE

You can use this package when you don't have the context too.
