我在从服务器获取数据时调用此对话框。该对话框周围有空格。我可以删除对话框周围的空白区域吗?这是我的代码。
var bodyProgress = new Container(
decoration: new BoxDecoration(
color: Colors.blue[200],
borderRadius: new BorderRadius.circular(10.0)
),
width: 300.0,
height: 200.0,
//color: Colors.blue,
alignment: AlignmentDirectional.center,
child: new Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Center(
child: new SizedBox(
height: 50.0,
width: 50.0,
child: new CircularProgressIndicator(
value: null,
strokeWidth: 7.0,
),
),
),
new Container(
margin: const EdgeInsets.only(top: 25.0),
child: new Center(
child: new Text(
"Signing up...",
style: new TextStyle(
color: Colors.white
),
),
),
),
],
),
);
我在这里调用这个对话框。我尝试过 AlertDialog() 和 SimpleDialog() ,但两者都有相同的问题。
showDialog(context: context, child: new AlertDialog(
content: bodyProgress,
));
