¿Cómo centrar verticalmente una columna en Flutter? He utilizado el widget "Centro nuevo". He utilizado el widget "nuevo centro", pero no centra verticalmente mi columna. Cualquier idea será de gran ayuda....
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Thank you"),
),
body: new Center(
child: new Column(
children: <Widget>[
new Padding(
padding: new EdgeInsets.all(25.0),
child: new AnimatedBuilder(
animation: animationController,
child: new Container(
height: 175.0,
width: 175.0,
child: new Image.asset('assets/angry_face.png'),
),
builder: (BuildContext context, Widget _widget) {
return new Transform.rotate(
angle: animationController.value * 6.3,
child: _widget,
);
},
),
),
new Text('We are glad we could serve you...', style: new TextStyle(
fontSize: 16.0,
fontWeight: FontWeight.w600,
color: Colors.black87),),
new Padding(padding: new EdgeInsets.symmetric(vertical: 5.0, horizontal: 0.0)),
new Text('We appreciate your feedback ! !', style: new TextStyle(
fontSize: 13.0,
fontWeight: FontWeight.w200,
color: Colors.black87),),
],
),
),
);
}
