I need shaking animation like this video
I'm newbie to Flutter. I would appreciate a solution or a link to the tutorial.
I think there can be better solution. But this one works fine, maybe it'll help
class TestAnimWidget extends StatefulWidget {
@override
State<StatefulWidget> createState() => _TestAnimWidgetState();
}
class _TestAnimWidgetState extends State<TestAnimWidget> with SingleTickerProviderStateMixin {
final TextEditingController textController = TextEditingController();
AnimationController controller;
@override
void initState() {
controller = AnimationController(duration: const Duration(milliseconds: 500), vsync: this);
super.initState();
}
@override
Widget build(BuildContext context) {
final Animation<double> offsetAnimation =
Tween(begin: 0.0, end: 24.0).chain(CurveTween(curve: Curves.elasticIn)).animate(controller)
..addStatusListener((status) {
if (status == AnimationStatus.completed) {
controller.reverse();
}
});
return Scaffold(
appBar: AppBar(),
body: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
AnimatedBuilder(
animation: offsetAnimation,
builder: (buildContext, child) {
if (offsetAnimation.value < 0.0) print('${offsetAnimation.value + 8.0}');
return Container(
margin: EdgeInsets.symmetric(horizontal: 24.0),
padding: EdgeInsets.only(left: offsetAnimation.value + 24.0, right: 24.0 - offsetAnimation.value),
child: Center(child: TextField(controller: textController, )),
);
}),
RaisedButton(onPressed: () {
if (textController.value.text.isEmpty) controller.forward(from: 0.0);
},
child: Text('Enter'),)
],
),
);
}
}
