【问题描述】：

在我的应用程序中，我使用了 WebViewController。但我不知道，如何将参数传递给标题。这显示一个错误。如何正确传递参数？请帮忙

class _PostRouteScreenState extends State<PostRouteScreen> 
final Completer<WebViewController> _controller = Completer<WebViewController>();
 @override
  void initState() 
    super.initState();
  
 @override
  void dispose() 
    super.dispose();
  
 @override
  Widget build(BuildContext context) 
    return Scaffold(
      appBar: new AppBar(),
body: WebView(
        initialUrl: 'https://....../make-route',
headers:"SB-app": "iphone",
        javascriptMode: JavascriptMode.unrestricted,
        onWebViewCreated: (WebViewController webViewController) 
         _controller.complete(webViewController);
        ,
navigationDelegate: (NavigationRequest request) 
          print('allowing navigation to $request');
          return NavigationDecision.navigate;
        ,
        onPageStarted: (String url) async 
          print('Page started loading: $url');
        ,
        onPageFinished: (String url) async 
          print('Page finished loading: $url');
        ,
        gestureNavigationEnabled: true,
      ),

【参考方案1】：

尝试省略初始 URL 并使用允许您传递标头的控制器：

  body: WebView(
    // initialUrl: 'https://....../make-route',
    // headers: "SB-app": "iphone",
    javascriptMode: JavascriptMode.unrestricted,
    onWebViewCreated: (WebViewController webViewController) 
      _controller.complete(webViewController);
      webViewController.loadUrl(
        'https://....../make-route',
        headers: "SB-app": "iphone",
      );
    ,
