因此，我在我的Flatter Web项目中实现了RazorPay支付网关。支付网关已成功实现。但我的问题是如何设置索引中定义的Javascript属性。html文件。

    ui.platformViewRegistry.registerViewFactory(viewId, cb);

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
        // This makes the visual density adapt to the platform that you run
        // the app on. For desktop platforms, the controls will be smaller and
        // closer together (more dense) than on mobile platforms.
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: RazorPayWeb(),
    );
  }
}

此外，该代码不处理razorpay_flatter插件，因为它不适用于flatter_Web。

使用srddoc属性，而不是iframelement对象的src属性来传递整个HTML内容。可以组合字符串插值来传递属性。

下面是一个例子：

//register view factory
    ui.platformViewRegistry.registerViewFactory("rzp-html",(int viewId) {
      IFrameElement element=IFrameElement();
      //Event Listener
      window.onMessage.forEach((element) {
        print('---------------------------Event Received in callback: ${element.data}');
        if(element.data=='MODAL_CLOSED'){
          Navigator.pop(context);
        }else if(element.data=='SUCCESS'){
          print('PAYMENT SUCCESSFULL!!!!!!!');
        }
      });

    element.requestFullscreen();
    // ****************** change you need to make *************
    element.srcdoc = '<html><p>Your entire HTML content with an ${attribute}</p></html>';
    element.style.border = 'none';
    return element;
  });
