如何在 Flutter 的另一个小部件下对齐小部件?
How to align widget under another widget in Flutter?
我有一个小部件用来表示进度
like this
我需要能够将名字放在气泡下,但是当我这样做时:
Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(
color: Colors.green,
width: 1.5,
),
),
height: MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 10,
child: Center(
child: Icon(
Icons.check,
color: Colors.green,
size: 30,
),
),
),
Text("Test label"),
],
),
this happens.
我也试过将条形与圆圈排成一行:
Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Row(
children: [
Container(
padding: EdgeInsets.symmetric(
vertical:
MediaQuery.of(context).size.height / 20,
),
height:
1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 16,
),
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(
color: mainColor,
width: 1.5,
),
),
height: MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 10,
child: Center(
child: Icon(
Icons.check,
color: mainColor,
size: 30,
),
),
),
Container(
padding: EdgeInsets.symmetric(
vertical:
MediaQuery.of(context).size.height /20,
),
height:
1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 16,
child: Container(
color: grey,
),
),
],
),
Text("Test label"),
],
),
This is better, but still creates problems if the text is bigger
如何对齐圆圈下方的文本而不导致线条出现问题?
整个widget的代码(抱歉这么长,不然不知道怎么显示):
Row(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Container(
padding: EdgeInsets.symmetric(
vertical:
MediaQuery.of(context).size.height / 20,
),
height:
1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 16,
),
Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(
color: Colors.green,
width: 1.5,
),
),
height: MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 10,
child: Center(
child: Icon(
Icons.check,
color: Colors.green,
size: 30,
),
),
),
Text("Test label"),
],
),Container(
padding: EdgeInsets.symmetric(
vertical:
MediaQuery.of(context).size.height / 20,
),
height:
1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 16,
child: Container(
color: Colors.grey,
),
),
Container(
padding: EdgeInsets.symmetric(
vertical: MediaQuery.of(context).size.height / 20,
),
height: 1 + MediaQuery.of(context).size.height / 10,
width: 3 / 2 * MediaQuery.of(context).size.width / 8,
child: Container(
color: Colors.grey,
),
),
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(
color: Colors.grey,
width: 1.5,
),
),
height: MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 10,
),
Container(
padding: EdgeInsets.symmetric(
vertical: MediaQuery.of(context).size.height / 20,
),
height: 1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 8,
child: Container(
color: Colors.grey,
),
),
Container(
padding: EdgeInsets.symmetric(
vertical: MediaQuery.of(context).size.height / 20,
),
height: 1 + MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 8,
child: Container(
color: Colors.grey,,
),
),
Container(
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(
color: Colors.grey,,
width: 1.5,
),
),
height: MediaQuery.of(context).size.height / 10,
width: MediaQuery.of(context).size.width / 10,
)
],
),
我建议的一个解决方案是尝试使用 ConstrainedBox
和 Container
包装文本并限制最大宽度。
例如-
ConstrainedBox(
constraints: BoxConstraints(maxWidth: 50),
child: Container(
child: Text('Your Text'),
),
),
认为如果文本太长而无法放在一行中,则将其移动到下一行。
