[英]How to add rounded corners to BottomAppBar with CircularNotchedRectangle in Flutter
[英]How to implement rounded bottomAppbar in flutter?
我想创建一个像这样的圆形底部应用栏。
圆形BottomAppBar:
但它看起来像这样......编码的BottomAppBar:
return ClipRRect(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(25),
topRight: Radius.circular(25),
bottomRight: Radius.circular(25),
bottomLeft: Radius.circular(25),
),
child: Padding(
padding: const EdgeInsets.only(bottom:20.0),
child: BottomAppBar(
shape: CircularNotchedRectangle(),
child: new Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
IconButton(
icon: Icon(Icons.menu),
color: Colors.white,
onPressed: () {},
),
IconButton(
icon: Icon(Icons.search),
color: Colors.white,
onPressed: () {},
),
],
),
color: Colors.blueGrey,
),
)
); ```
应用栏小部件有一个 shape 属性,您应该使用它来获得所需的结果,将您的代码更改为此
BottomAppBar(
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(
topLeft: Radius.circular(25),
topRight: Radius.circular(25),
bottomRight: Radius.circular(25),
bottomLeft: Radius.circular(25),
),
),
... //Your codes
),
正如@Jagadish 建议的那样,我使用Shape: RoundedRectangleBorder
RoundedRectangleBorder 来获得圆角的 BottomAppBar。 但是,为了获得缺口条,我使用了:
shape: AutomaticNotchedShape(
RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(25),
),
StadiumBorder(),
),
... //Codes=
),
这也为扩展浮动操作按钮和(我认为)具有差异形状的按钮提供了一个档次。
