如何使底部 FAB 像下面的图像一样?
这是我当前的代码示例:
(for tumbling window $window in ('Cat', 'likes', 'fish', 'Dog', 'likes', 'bones')
start at $s when $s mod 3 = 1
return
string-join($window)
)
! bs:next-function(.)
我尝试了很多但没有运气:(有什么解决方法吗?谢谢您的建议:)

无法设置FAB的尺寸。相反,您必须使用RawMaterialButton
,复制FAB的默认属性并更改大小:
@override
Widget build(BuildContext context) {
return Scaffold(
body: Stack(
alignment: Alignment.bottomCenter,
children: <Widget>[
CustomScrollView(
slivers: <Widget>[
...
],
),
RawMaterialButton(
elevation: 6,
highlightElevation: 12.0,
constraints: BoxConstraints(
minHeight: 48.0,
minWidth: double.infinity,
maxHeight: 48.0,
),
fillColor: Theme.of(context).accentColor,
textStyle: Theme.of(context).accentTextTheme.button.copyWith(
color: Theme.of(context).accentIconTheme.color,
letterSpacing: 1.2,
),
child: Text("SAVE THE CHANGE"),
onPressed: () {},
)
],
),
);
}
