If you want to create a dialog that is able to accept text input and show result in flutter? This is a quick ugly example for what you are asking for, to just pass the concept around:
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 | class DialogExample extends StatefulWidget { @override _DialogExampleState createState() => new _DialogExampleState(); } class _DialogExampleState extends State<DialogExample> { String _text = "initial"; TextEditingController _c; @override initState(){ _c = new TextEditingController(); super.initState(); } @override Widget build(BuildContext context) { return new Scaffold( body: new Center( child: new Column( mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[ new Text(_text), new RaisedButton(onPressed: () { showDialog(child: new Dialog( child: new Column( children: <Widget>[ new TextField( decoration: new InputDecoration(hintText: "Update Info"), controller: _c, ), new FlatButton( child: new Text("Save"), onPressed: (){ setState((){ this._text = _c.text; }); Navigator.pop(context); }, ) ], ), ), context: context); },child: new Text("Show Dialog"),) ], ) ), ); } } |
