In this post, I'm going to show you how to show a Dialog box on a Button Click. The final output is going to look like below. On button click, you will see the Dialog box shown below.
);
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State {
void _showcontent() {
showDialog(
context: context, barrierDismissible: false, // user must tap button!
builder: (BuildContext context) {
return new AlertDialog(
title: new Text('You clicked on'),
content: new SingleChildScrollView(
child: new ListBody(
children: [
new Text('This is a Dialog Box. Click OK to Close.'),
],
),
),
actions: [
new FlatButton(
child: new Text('Ok'),
onPressed: () {
Navigator.of(context).pop();
},
),
],
);
},
);
}
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
new Text(
'Push the button to show a Dialog:',
),
new RaisedButton(
onPressed: _showcontent,
color: Colors.blueAccent,
child:
new Text('Click here', style: TextStyle(color: Colors.white)),
),
],
),
),
);
}
}
Let me know if this helps through your comments.
