我的 CustomChip
有一个问题:
我只需要包装卡片以适合内容。
但是,我还有第二个要求:长文本应该溢出淡入淡出。
当我解决第二个问题时,当我添加 Expanded
时,这个问题开始出现。包裹内部Row
我不明白为什么内部Row
虽然它的 mainAxisSize
似乎也在扩大已经设置为 min
这是代码:
屏幕:
import 'package:flutter/material.dart';
import 'package:app/common/custom_chip.dart';
class RowInsideExpanded extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Container(
decoration: BoxDecoration(
border: Border.all(
width: 1.0,
),
),
width: 200.0,
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
_buildChip('short'),
_buildChip('looooooooooooooooooooooongg'),
],
),
),
),
);
}
_buildChip(String s) {
return Row(
children: [
Container(
color: Colors.red,
width: 15,
height: 15,
),
Expanded(
child: CustomChip(
elevation: 0.0,
trailing: Container(
decoration: BoxDecoration(
color: Colors.grey,
shape: BoxShape.circle,
),
child: Icon(Icons.close),
),
onTap: () {},
height: 42.0,
backgroundColor: Colors.black12,
title: Padding(
padding: const EdgeInsets.symmetric(horizontal: 8.0),
child: Text(
s,
softWrap: false,
overflow: TextOverflow.fade,
style: TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 16.0),
),
),
),
),
],
);
}
}
和 CustomChip
import 'package:flutter/material.dart';
class CustomChip extends StatelessWidget {
final Widget leading;
final Widget trailing;
final Widget title;
final double height;
final double elevation;
final Color backgroundColor;
final VoidCallback onTap;
const CustomChip({
Key key,
this.leading,
this.trailing,
this.title,
this.backgroundColor,
this.height: 30.0,
this.elevation = 2.0,
this.onTap,
}) : super(key: key);
@override
Widget build(BuildContext context) {
return Card(
elevation: elevation,
color: backgroundColor,
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.circular(30.0),
),
child: InkWell(
onTap: onTap,
child: Container(
height: height,
child: Padding(
padding: const EdgeInsets.only(left: 5.0, right: 5.0),
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
leading ?? Container(),
SizedBox(
width: 5.0,
),
Flexible(
child: title,
fit: FlexFit.loose,
),
SizedBox(
width: 5.0,
),
trailing ?? Container(),
],
),
),
),
),
);
}
}
最佳答案
查找“MainAxisSize”属性并设置为“MainAxisSize.min”
