  Widget build(BuildContext context) {
    return const FlutterSimpleWebView(
      url: 'https://flutter.dev',
      title: 'Flutter Website',
    );

}

2. Advanced / ERP Configuration

FlutterSimpleWebView(
  url: 'https://my-odoo-erp.com',
  title: 'Company Portal',
  showAppBar: true,

🧠 How It Works

Connectivity Management

Unlike many packages that rely on heavy plugins, this package uses a raw internet probe (InternetAddress.lookup). It detects true internet access (not just Wi-Fi connection) and handles offline states with a polished UI.

File Handling

• Uploads: Automatically triggers the native OS file picker when the WebView requests a file selector.
• Downloads: Intercepts URLs with common file extensions. It preserves session cookies to ensure you can download files from password-protected ERP sections.
