Flutter路由跳转
基本路由跳转
ElevatedButton(
onPressed: () {
//基本路由跳转
Navigator.of(context).push(
MaterialPageRoute(builder: (BuildContext context) {
return const SearchPage();
}),
);
},
child: const Text("基本路由跳转"),
),search.dart页面
import 'package:flutter/material.dart';
class SearchPage extends StatefulWidget {
final String context;
final int aid;
const SearchPage({
super.key,
this.context = "",
this.aid = 0,
});
@override
State<SearchPage> createState() => _SearchPageStateState();
}
class _SearchPageStateState extends State<SearchPage> {
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
floatingActionButton: FloatingActionButton(
onPressed: () {
//返回到上一页路由
Navigator.pop(context);
},
child: const Icon(Icons.close),
),
appBar: AppBar(
title: const Text("搜索页面"),
),
body: Center(
child: Text(
"${widget.context} "
"${widget.aid == 0 ? "" : ",代号：${widget.aid}"}"
),
),
);
}
}
返回上一页路由
Navigator.pop(context);基本路由跳转传参
ElevatedButton(
onPressed: () {
//基本路由跳转传参
Navigator.of(context).push(
MaterialPageRoute(builder: (BuildContext context) {
return const SearchPage(
context: "首页传过来的参数", aid: 123456);
}),
);
},
child: const Text("基本路由跳转传参"),
),命名路由跳转
ElevatedButton(
onPressed: () {
//命名路由跳转
Navigator.pushNamed(context, "/search");
},
child: const Text("命名路由跳转"),
),命名路由跳转需要先配置路由
routers.dart配置文件
import 'package:flutter/material.dart';
import 'package:flutter_demo/form.dart';
import 'package:flutter_demo/register2.dart';
import 'package:flutter_demo/search.dart';
//配置路由
Map routes = {
"/search": (context) => const SearchPage(),
"/register2": (context) => const Register2(),
"/form": (context, {arguments}) => FormPage(arguments: arguments),
};
//配置onGenerateRoute固定写法,这个方法相当于一个中间件，可以做权限判断
var onGenerateRoute = (RouteSettings settings) {
final String? name = settings.name;
final Function? pageContentBuilder = routes[name];
if (pageContentBuilder != null) {
if (settings.arguments != null) {
final Route route = MaterialPageRoute(
builder: (context) =>
pageContentBuilder(context, arguments: settings.arguments),
);
return route;
} else {
final Route route = MaterialPageRoute(
builder: (context) => pageContentBuilder(context),
);
return route;
}
}
return null;
};
然后需要在首页添加initialRoute和onGenerateRoute配置
import 'package:flutter_demo/routers/routers.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
//隐藏DEBUG图标
debugShowCheckedModeBanner: false,
theme: ThemeData(primarySwatch: Colors.blue),
home: const Scaffold(
body: MyHomePage(),
),
initialRoute: "/",
onGenerateRoute: onGenerateRoute,
);
}
}命名路由跳转传参
ElevatedButton(
onPressed: () {
//命名路由传参
Navigator.pushNamed(
context,
"/form",
arguments: {
"aid": 123456,
"name": "张三",
"age": "18",
},
);
},
child: const Text("命名路由传参"),
),context属性中写配置中的路径，arguments属性中是跳转需要带的参数，跳转到form.dart页面并接收参数。
import 'package:flutter/material.dart';
class FormPage extends StatefulWidget {
final Map arguments;
const FormPage({
super.key,
required this.arguments,
});
@override
State<FormPage> createState() => _FormPageStateState();
}
class _FormPageStateState extends State<FormPage> {
@override
void initState() {
super.initState();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text("表单页面"),
),
body: Center(
child: Text(
widget.arguments.isEmpty
? ""
: "我是${widget.arguments["name"]},我${widget.arguments["age"]}了，"
"代号：${widget.arguments["aid"]}",
),
),
);
}
}
命名路由替换跳转
Navigator.of(context).pushReplacementNamed("/register2");命名路由替换跳转用pushReplacementNamed，跳转新页面后本页面被替换掉。文章来源：https://www.toymoban.com/news/detail-756226.html
移除所有页面返回到根页面
Navigator.of(context).pushAndRemoveUntil(
MaterialPageRoute(builder: (BuildContext context) {
return const MyApp();
}), (route) => false);移除所有页面并返回到指定页面用pushAndRemoveUntil。文章来源地址https://www.toymoban.com/news/detail-756226.html
