如何在Flutter中定位这些图标？
如何在Flutter中定位这些图标？
提问于 2019-09-26 19:17:21
我正在尝试从Gmail重新创建布局，但我不知道如何在布局中定位图标。
这是我想让这些图标看起来像的图片：
这是我在Flutter中已经做过的一张图片：
我希望图标之间有一个空间，我希望他们在同一高度的"McDonald波兰“。
有没有人能帮我？
代码：
import 'package:flutter/material.dart';
class GeneratedMailCouponScreen extends StatelessWidget {
final String couponImage;
GeneratedMailCouponScreen({Key key, @required this.couponImage}) : super(key: key);
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
body: SafeArea(
child: Container(
padding: EdgeInsets.all(16.0),
child: Column(
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Row(
children: [
Icon(
Icons.arrow_back
)
],
),
Row(
children: [
Icon(
Icons.archive
),
SizedBox(width: 5.0),
Icon(
Icons.delete
),
SizedBox(width: 5.0),
Icon(
Icons.mail

这是工作！你必须把'M‘Container放在Row里面，把图标放在Container里面
return Scaffold(
body: Container(
padding: EdgeInsets.only(top: 50),
child: new Column(
mainAxisAlignment: MainAxisAlignment.start,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.end,
children: [
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.end,
children: [
Container(
height: 45.0,
width: 45.0,
decoration: BoxDecoration(
color: Colors.blue[100], shape: BoxShape.circle),
child: Center(
child: Text(
'M',
style: TextStyle(fontSize: 20.0),
),
)),
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
children: [
Text('McDonalds Poland',
style: TextStyle(color: Colors.black)),
SizedBox(width: 8.0),
Text('Wczoraj',
style: TextStyle(color: Colors.grey))
],
),
Row(
children: [
Text('do mnie',
style: TextStyle(color: Colors.grey)),
Icon(Icons.expand_more)
],
)
],
),
],
),
Container(
padding: EdgeInsets.only(top: 50),
child: Row(
children: [
Icon(Icons.reply),
Icon(Icons.more_vert)
],
),
)
],
)
])),
);
