【中文标题】Flutter/ 3 Rows in one Container 或 AlertDialog【英文标题】:Flutter/ 3 Rows in one Container or AlertDialog 【发布时间】:2021-07-05 14:48:18 【问题描述】:我正在尝试制作一个带有导航窗口的警报对话框。应该有 3 行具有不同的 IconButtons 在另一个站点上导航。不幸的是,我是 Flutter 的新手,不知道如何再制作 2 行。有人可以帮帮我吗?甚至有可能做到这一点吗?我的意思是我不能再添加任何孩子,或者我可以吗?我不知道我是否应该将其拆分为 3 个 AlertDialogs 还是那样愚蠢?
That was my Layout for the first Row
This is what it should look like but with 3 lines and not two, so that the code that i have right now can be copied to make 3 identical rows parallel
代码:
import 'package:flutter/material.dart';
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
void popup(BuildContext context)
var alertDialog = AlertDialog(
backgroundColor: Color(0xffb09c84),
title: Text(''),
content: Container(
constraints: BoxConstraints(minWidth: 0, maxWidth: 300, maxHeight: 600),
padding: EdgeInsets.all(0),
width: 300.0,
height: 560.0,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: [
Column(
children: [
IconButton(
icon: FaIcon(
FontAwesomeIcons.newspaper,
size: 44.0,
),
onPressed: () ,
),
SizedBox(height: 2.0),
Container(
child: Text(
" Zeitung",
style: TextStyle(
fontSize: 14.0,
),
),
),
],
),
Column(
children: [
IconButton(
icon: FaIcon(
FontAwesomeIcons.envelope,
size: 44.0,
),
onPressed: () ,
),
SizedBox(height: 2.0),
Container(
child: Text(
" News",
textAlign: TextAlign.center,
style: TextStyle(
fontSize: 14.0,
),
),
),
],
),
Column(
children: [
IconButton(
icon: FaIcon(
FontAwesomeIcons.creativeCommonsSampling,
color: Colors.black,
size: 44.0,
),
onPressed: () ,
),
SizedBox(
height: 3.0,
),
Container(
child: Text(
" Vertretung",
style: TextStyle(
fontSize: 14.0,
),
),
),
],
),
],
),
),
);
showDialog(context: context, builder: (BuildContext context) => alertDialog);
【问题讨论】:
【参考方案1】:这是你的代码:
Container(
constraints: BoxConstraints(minWidth: 0, maxWidth: 300, maxHeight: 600),
padding: EdgeInsets.all(0),
width: 300.0,
height: 560.0,
child: //Row(..the rest you want to copy"
在此行之前添加一列,并复制您的Row
三次:
Container(
constraints: BoxConstraints(minWidth: 0, maxWidth: 300, maxHeight: 600),
padding: EdgeInsets.all(0),
width: 300.0,
height: 560.0,
child: Column( children: [
Row1("..the rest you want to copy"),
Row2("..the rest you want to copy"),
Row3("..the rest you want to copy)"
]), //Column
), //Container
