Issue
Created counter app with one floating action button.
If i want to add one more button for reset the counter, where can i add second floating action button at bottom bar?
Also i have to add any method in void section or is there any reset counter function available?
import 'package:flutter/material.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Counter App',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Counter App'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Text('You have pressed the button $_counter times.'),
),
bottomNavigationBar: BottomAppBar(
child: Container(
height: 50.0,
),
),
floatingActionButton: FloatingActionButton(
onPressed: () => setState(() {
_counter++;
}),
tooltip: 'Increment Counter',
child: Icon(Icons.add),
),
floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
);
}
}
Solution
You can use the flutter_speed_dial package: https://pub.dartlang.org/packages/flutter_speed_dial
On the link above have a example showing how to use it. You must use SpeedDial
class and on children[]
you can add some buttons with SpeedDialChild
. The sample below shows 2 FABs.
Example using it:
Widget _getFAB() {
return SpeedDial(
animatedIcon: AnimatedIcons.menu_close,
animatedIconTheme: IconThemeData(size: 22),
backgroundColor: Color(0xFF801E48),
visible: true,
curve: Curves.bounceIn,
children: [
// FAB 1
SpeedDialChild(
child: Icon(Icons.assignment_turned_in),
backgroundColor: Color(0xFF801E48),
onTap: () { /* do anything */ },
label: 'Button 1',
labelStyle: TextStyle(
fontWeight: FontWeight.w500,
color: Colors.white,
fontSize: 16.0),
labelBackgroundColor: Color(0xFF801E48)),
// FAB 2
SpeedDialChild(
child: Icon(Icons.assignment_turned_in),
backgroundColor: Color(0xFF801E48),
onTap: () {
setState(() {
_counter = 0;
});
},
label: 'Button 2',
labelStyle: TextStyle(
fontWeight: FontWeight.w500,
color: Colors.white,
fontSize: 16.0),
labelBackgroundColor: Color(0xFF801E48))
],
);
}
