If you want to create Toast in Flutter? You can access the parent ScaffoldState using Scaffold.of(context), Then do something like below example:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 | import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( home: const Home(), ); } } class Home extends StatelessWidget { const Home({ Key key, }) : super(key: key); @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text('Snack bar'), ), /// We use [Builder] here to use a [context] that is a descendant of [Scaffold] /// or else [Scaffold.of] will return null body: Builder( builder: (context) => Center( child: RaisedButton( child: const Text('Show toast'), onPressed: () => _showToast(context), ), ), ), ); } void _showToast(BuildContext context) { final scaffold = Scaffold.of(context); scaffold.showSnackBar( SnackBar( content: const Text('Added to favorite'), action: SnackBarAction( label: 'UNDO', onPressed: scaffold.hideCurrentSnackBar), ), ); } } |
