callback url in Flutter-CodePudding

I'm working on the Flutter app, and need to create a callback url after a customer success/fails payment. Which event/function can be used with webview_flutter?

I was check the same questions here but didn't find solutions

CodePudding user response：

You can create webview client and use shouldOverrideUrlLoading or onLoadResource to create a callback url in webview_flutter

CodePudding user response：

You can use webview_flutter and do what you want in navigationDelegate callback

WebView(
                initialUrl: yourPaymenntUrl,
                javascriptMode: JavascriptMode.unrestricted,
                navigationDelegate: (navigationDelegate) async {

                  if (navigationDelegate.url
                      .contains(yourReturnUrl)) {
                    // payment completed
                    // do what ever you want
                   String? merchantId = Uri.parse(navigationDelegate.url)
                   .queryParameters['merchantId'];
                    Navigator.pop(context, merchantId);
                  } else if (navigationDelegate.url
                      .contains(cancelUrl)) {
                    // TODO implementation
                   Navigator.pop(context);
                  }

                  return NavigationDecision.navigate;
                },
              )
