dependencies:
  flutter:
    sdk: flutter
  webview_flutter: ^2.0.0

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class LocalHtmlPage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Local HTML Page'),
      ),
      body: WebView(
        initialUrl: 'assets/local.html',
        javascriptMode: JavascriptMode.unrestricted,
      ),
    );
  }
}

Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => LocalHtmlPage()),
);
