在Flutter Navigator 2.0 中,可以动态设置页面标题。为了在Flutter Web中显示页面标题(即在浏览器标签中显示),我们可以使用Flutter的插件flutter_web_
pl
ugins和html。以下是解决问题的步骤:
在pubspec.yaml文件中添加以下依赖项:
dependencies:
flutter_web_plugins: ^0.0.0
html: ^0.14.0+3
在main.dart文件中,我们需要注册一个Flutter插件,该插件将允许我们在Flutter Web中访问当前URL和更改页面标题。
import 'package:flutter_web_plugins/flutter_web_plugins.dart';
import 'package:html/html.dart' as html;
void main() {
// Register the url_strategy plugin
setUrlStrategy(PathUrlStrategy());
// Register a plugin to access the current URL and change page title
UrlPlugin.registerUrlPlugin();
class UrlPlugin {
static void registerUrlPlugin() {
final UrlPlugin instance = UrlPlugin();
// Register the plugin
html.window.history.pushState(null, '', html.window.location.href);
setUrlStrategy(instance);
String getUrl() => html.window.location.pathname;
void setUrl(String url) {
html.window.history.pushState(null, '', url);
html.document.title = getTitleFromUrl(url); // Set page title
String getTitleFromUrl(String url) {
String title = '';
// Parse the URL to extract the page title
return title;
现在,我们可以在Flutter Web应用程序中使用我们自己的导航器。在导航器中,我们需要使用NavigatorObservers来监视路由更改,并使用我们的UrlPlugin来更改页面标题。
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Web',
navigatorObservers: [
MyRouteObserver(),
onGenerateRoute: (RouteSettings settings) {
// Generate routes
