Create a basic counter page:
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);

final String title;

@override
_MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;

void _incrementCounter() {
setState(() {
_counter++;
});
}

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text(
'You have pushed the button this many times:',
),
Text(
'$_counter',
style: Theme.of(context).textTheme.headline4,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: Icon(Icons.add),
),
);
}
}
copied to clipboard
Move the Floating Action Button to AssistiveTouch:
class _MyHomePageState extends State<MyHomePage> {
@override
Widget build(BuildContext context) {
// Wrap with a [Stack] widget first
return Stack(
children: [
Scaffold(
// ...
),
AssistiveTouch(
// move floatingActionButton here
child: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: Icon(Icons.add),
),
)
],
);
}
}
copied to clipboard
Now you have a draggable Floating Action Button!
