how to put snackbar without any button press in flutter? code example
Example: how to show snackbar in flutter
You can show material design snackbars using the following code:
Scaffold.of(context).showSnackBar(SnackBar(
content: Text("New Notification"),
));
In some cases, this will throw an error and it can be resolved using a workaround:
GlobalKey<ScaffoldState> _scaffoldKey = GlobalKey<ScaffoldState>();
Scaffold(
key: _scaffoldKey,
body: ...
)
_scaffoldKey.showSnackBar(SnackBar(
content: Text("New Notification"),
));
