Question

我正在尝试从Flutter应用程序的webView中打开付款网址链接，但在输入输入字段时崩溃了。

return Scaffold(
          body: new MyWebView(
            selectedUrl:"https://easternbank.ap.gateway.mastercard.com/checkout/pay/SESSION0002887307683L1130761K87",),
        );

我们的MyWebView小部件是：

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class MyWebView extends StatelessWidget {
  final String selectedUrl;
  final Completer<WebViewController> _controller =  Completer<WebViewController>();
  MyWebView({
    @required this.selectedUrl,
  });

  @override
  Widget build(BuildContext context) {
    bool isLoading = true;
    return StatefulBuilder(
        builder: (BuildContext context, StateSetter setState) {
          return Scaffold(
            body: Stack(
              children: <Widget>[
                //new LinearProgressIndicator(),
                new WebView(
                  initialUrl: selectedUrl,
                  javascriptMode: JavascriptMode.unrestricted,
                  onWebViewCreated: (WebViewController webViewController) {
                    _controller.complete(webViewController);
                  },
                  onPageFinished: (finised) {
                    setState(() {
                      isLoading = false;
                    });
                  },
                ),
                isLoading ? _loadingScreen() : Container(),
              ],
            ),
          );
        });
  }

用于安全付款页面的webView是否存在任何问题？

通常是在尝试在页面中输入内容时发生的

一些调试错误：

安全付款页面的webView是否存在任何问题？

不。但是，当网页中包含 DropDown 时，此功能目前不起作用。

不幸的是，由于您的应用在下拉菜单中崩溃，因此官方插件未解决此问题，此问题正在here和here进行讨论，尚未解决，

所以我建议使用flutter_webview_plugin

示例

 WebviewScaffold(
      url: "https://easternbank.ap.gateway.mastercard.com/checkout/pay/SESSION0002887307683L1130761K87",
      ),
