推荐答案

我找到了一个解决方案，它对我有用！

I found a solution and it worked for me!

InAppWebView

扑朔迷离以打开Paytabs交易页面.交易成功后，它将我重定向到return_url.InAppWebView有一个方法

In flutter to open the paytabs transaction page. When the transaction is successful, it redirects me to a return_url. InAppWebView has a method

onLoadStart:(InAppWebViewController控制器，字符串url)

在这种方法中，我检查了returl_url == url并重定向到我的应用程序，并相应地关闭了InAppWebView.

In this method, I checked if the returl_url == url and redirected to my app and closed the InAppWebView accordingly.

onLoadStart: (InAppWebViewController controller, String url) {
          setState(() {
            _con.url = url;
          });
          if (url == "return_url") {
            //close the webview
            _con.webView.goBack();

            //navigate to the desired screen with arguments
            Navigator.of(context).pushReplacementNamed('/OrderSuccess',
                arguments:
                    new RouteArgument(param: 'Credit Card (Paytabs)'));
          }
        },
