  final Size viewportSize = queryData.size;

  return Scaffold(
      body: Center(
    child: Column(
      children: [
        WebF(
          devToolsService: ChromeDevToolsService(), // Enable Chrome DevTools Services
          viewportWidth: viewportSize.width - queryData.padding.horizontal, // Adjust the viewportWidth
          viewportHeight: viewportSize.height - queryData.padding.vertical, // Adjust the viewportHeight
          bundle: WebFBundle.fromUrl('https://andycall.oss-cn-beijing.aliyuncs.com/demo/demo-vue.js'), // The page entry point
        ),
      ],
    ),
  ));
}

How it works

WebF provides a rendering engine which follows the W3C standards like web browsers do. It can render HTML/CSS and execute JavaScript. It's built on top of the flutter rendering pipelines and implements its own layout and painting algorithms.

With WebF, Web Apps and Flutter Apps share the same rendering context. It means that you can use Flutter Widgets to define your HTML elements and embed your Web App as a Flutter Widget in your flutter apps.
