[英]how can i build white region of this screen using flutter?
我是 Flutter 框架的新手,我想创建以下活动,我知道如何创建活动永久区域但我不知道这个屏幕的白色部分,这个屏幕中使用的小部件是什么,请指导我如何我可以使用 Flutter 创建这部分吗?
这是我的代码
import 'package:flutter/material.dart';
import 'bottomnavigationbar.dart';
class Contact extends StatefulWidget {
@override
_ContactState createState() => _ContactState();
}
class _ContactState extends State<Contact> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Contact"),
),
body: Container(
padding: EdgeInsets.all(1),
color: Colors.black,
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
Container(
width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.width/1.6,
// constraints: BoxConstraints.expand(),
decoration: BoxDecoration(
image: DecorationImage(
image: AssetImage("images/contactpage.png"),
fit: BoxFit.cover),
),
),
Padding(
padding: EdgeInsets.all(8),
),
Text(
"Contact Info",
style: TextStyle(
color: Colors.red,
fontSize: 20,
fontWeight: FontWeight.w400,
),
),
Padding(
padding: EdgeInsets.all(8),
),
Divider(
color: Colors.white,
indent: 40,
endIndent: 40,
),
],
),
),
bottomNavigationBar: BottomNavigation(),
);
}
}
试试这个例子
import 'package:flutter/material.dart';
class UsingAlertDialog extends StatefulWidget{
@override
UsingAlertDialogState createState()=> new UsingAlertDialogState();
}
class UsingAlertDialogState extends State<UsingAlertDialog>{
AlertDialog dialog = new AlertDialog(
content: new Text(
"I'm a AlertDialog",
style: new TextStyle(fontSize: 30.0),
),
);
@override
Widget build(BuildContext context){
return Scaffold(
appBar: new AppBar(
title: new Text("Using Alert Dialog"),
),
body: new Container(
child: new Center(
child: new RaisedButton(
child: new Text("Touch Me"),
onPressed: (){
showDialog(
context: context,
builder: (BuildContext context)=>dialog
);
},
),
),
),
);
}
}
========= 更新 ========
model 组件可以是自定义对话框SimpleDialog
关于电话你可以使用这个 package url_launche
