Flutter:居中的 CircleAvatar 旁边的位置图标
Flutter: Position Icon next to a centered CircleAvatar
我想在居中的圆形头像旁边的右上角放置一个编辑图标。但是,如果我在 Row Widget 中使用 Center Widget,它就不起作用:
Row(
children: <Widget>[
Center(
child:
CircleAvatar(
radius: 70,
backgroundImage: NetworkImage(
""),
),
),
Icon(Icons.edit),
],
)
如果我使用 mainaxisalignment 将行内容居中,它不会使头像居中,而是头像与图标一起居中:
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
CircleAvatar(
radius: 70,
backgroundImage: NetworkImage(
"https://autix.ch/wp-content/uploads/profile-placeholder.png"),
),
Icon(Icons.edit),
],
),
It should look like this:
尝试使用堆栈:
Container(
width: 200,
height: 200,
child: Stack(
children: <Widget>[
Align(
alignment: Alignment.topRight,
child: Icon(Icons.access_time),
),
Container(
width: 200,
height: 200,
child: CircleAvatar(
child: Text('Avatar'),
),
),
],
),
),
结果:
您可以使用容器小部件包裹编辑图标,并将其与右上角对齐,如下所示:
Container(
height: 140,
alignment: Alignment.topRight,
child: Icon(Icons.edit),
),
不用容器也可以:
CircleAvatar(
backgroundImage: NetworkImage(photoURL),
child: Stack(
children: [
Align(
alignment: Alignment.topRight,
child: Icon(Icons.ac_unit),
)
],
),
),
