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,
      ),

【解决方案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"},
      );
    },
