Meta SEO は、Web アプリケーション向けに設計されたFlutterパッケージで、ドキュメントヘッド内のHTMLメタタグを動的に管理するためのものです。開発者がタイトル、説明、キーワード、Open Graphプロパティなどのメタデータを設定することで、検索エンジン最適化(SEO)を強化できます。このパッケージはFlutter Webプロジェクトにスムーズに統合され、DOMの手動操作なしにSEO要素を簡単にカスタマイズできるようにします。Web、Android、iOS、macOS、Windows、Linuxなど、すべての主要プラットフォームをサポートしており、強力なSEOパフォーマンスを必要とするクロスプラットフォームWebアプリに最適です。
Then add the config MetaSEO method before the running of the Flutter app into main.dart file:
voidmain() {
// It is required to add the following to run the meta_seo package correctly// before the running of the Flutter appif (kIsWeb) {
MetaSEO().config();
}
runApp(constMyApp());
}
Finally add MetaSEO into your target web pages:
@overrideWidgetbuild(BuildContext context) {
// Add MetaSEO just into Web platform conditionif(kIsWeb) {
// Define MetaSEO objectMetaSEO meta = MetaSEO();
// add meta seo data for web app as you want
meta.author(author: 'Eng Mouaz M AlShahmeh');
meta.description(description: 'Meta SEO Web Example');
meta.keywords(keywords: 'Flutter, Dart, SEO, Meta, Web');
}
returnconstScaffold(
body: Center(child: Text('Meta SEO Web Example')),
);
}
Other example with GoRouter package
First: Add to pubspec.yaml:
dependencies:meta_seo:^3.0.9go_router:^5.2.0# Add the latest version
Second: The same as before and add the config MetaSEO method before the running of the Flutter app into main.dart file:
voidmain() {
// It is required to add the following to run the meta_seo package correctly// before the running of the Flutter appif (kIsWeb) {
MetaSEO().config();
}
runApp(constMyApp());
}
Then follow GoRouter configuration steps and latest add MetaSEO into your GoRouter as you want:
final router = GoRouter(
initialLocation: '/',
routes: <GoRoute>[
GoRoute(
path: '/',
builder: (BuildContext context, GoRouterState state) {
// Add MetaSEO just into Web platform conditionif(kIsWeb) {
// Define MetaSEO objectMetaSEO meta = MetaSEO();
// add meta seo data for web app as you want
meta.ogTitle(ogTitle: 'First Screen');
meta.description(description: 'First Screen');
meta.keywords(keywords: 'Flutter, Dart, SEO, Meta, Web');
}
returnconstFirstScreen();
},
),
GoRoute(
path: '/second_screen',
builder: (BuildContext context, GoRouterState state) {
// Add MetaSEO just into Web platform conditionif(kIsWeb) {
// Define MetaSEO objectMetaSEO meta = MetaSEO();
// add meta seo data for web app as you want
meta.ogTitle(ogTitle: 'Second Screen');
meta.description(description: 'Second Screen');
meta.keywords(keywords: 'Flutter, Dart, SEO, Meta, Web');
}
returnconstSecondScreen();
},
),
],
);
Extended MetaSEO tags
If you want to use Open Graph or Twitter Card meta tags
Note: You must be in live server not as a local host.
Note: The package delete any duplicated meta tags and keep the latest in order.
The same as before and if you want to use any tags does not exist into the main package
methods just add extended tags as the below:
@overrideWidgetbuild(BuildContext context) {
// Add MetaSEO just into Web platform conditionif(kIsWeb) {
// Define MetaSEO objectMetaSEO meta = MetaSEO();
// add meta seo open graph tags as you want
meta.facebookAppID(facebookAppID: 'your_app_id');
meta.ogTitle(ogTitle: 'Example Screen');
meta.ogDescription(ogDescription: 'Example Screen Description');
meta.ogImage(ogImage: 'https://example.com/example.png');
// here you can add any tags does not exist in the package as this
meta.propertyContent(property: 'og:site_name', content: 'example');
// or if you want to add twitter card meta tags just as the following
meta.twitterCard(twitterCard: TwitterCard.summaryLargeImage);
meta.twitterTitle(twitterTitle: 'Example Screen');
meta.twitterDescription(twitterDescription: 'Example Screen Description');
meta.twitterImage(twitterImage: 'https://example.com/example.png');
// here you can add any tags does not exist in the package as this
meta.nameContent(name: 'twitter:site', content: '@mouaz_m_shahmeh');
}
returnconstScaffold(
body: Center(child: Text('Extended Meta SEO Web Example')),
);
}
