Second: Add to pubspec.yaml:

dependencies:
  meta_seo: ^1.0.5

Then import it to your project:

import 'package:meta_seo/meta_seo.dart';
import 'package:flutter/foundation.dart';

Finally add MetaSEO into your target web pages:

@override
Widget build(BuildContext context) {

  // Add MetaSEO just into Web platform condition
  if(kIsWeb) {
    // Define MetaSEO object
    MetaSEO meta = MetaSEO();
    // add meta seo data for web app as you want
    meta.seoAuthor('Eng Mouaz M AlShahmeh');
    meta.seoDescription('Meta SEO Web Example');
    meta.seoKeywords('Flutter, Dart, SEO, Meta, Web');
  }

  return const Scaffold(
    body: Center(child: Text('Meta SEO Web Example')),
  );
}

Other example with GoRouter package

First: The same as before

Second: Add to pubspec.yaml:

dependencies:
  meta_seo: ^1.0.5
  go_router: ^5.2.0 # Add the latest version

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 condition
        if(kIsWeb) {
          // Define MetaSEO object
          MetaSEO meta = MetaSEO();
          // add meta seo data for web app as you want
          meta.seoOGTitle('First Screen');
          meta.seoDescription('First Screen');
          meta.seoKeywords('Flutter, Dart, SEO, Meta, Web');
        }

        return const FirstScreen();
      },
    ),
    GoRoute(
      path: '/second_screen',
      builder: (BuildContext context, GoRouterState state) {
        // Add MetaSEO just into Web platform condition
        if(kIsWeb) {
          // Define MetaSEO object
          MetaSEO meta = MetaSEO();
          // add meta seo data for web app as you want
          meta.seoOGTitle('Second Screen');
          meta.seoDescription('Second Screen');
          meta.seoKeywords('Flutter, Dart, SEO, Meta, Web');
        }

        return const SecondScreen();
