paypal - 通过webview flutter paypal

我试图整合贝宝付款为我的颤动应用程序通过WebVIEW。

return new MaterialApp(
routes: {
"/": (_) => new WebviewScaffold(
  url: "https://www.paypal.com/cgi-bin/webscr?    business=xxxx.com&cmd=_xclick&item_name=Hot+Sauce-12oz.+Bottle&amount=5.95&currency_code=USD",
  appBar: new AppBar(
    title: new Text(
      "Payment",
    ),
  ),
)
},
);

当我运行页面时，应用程序意外关闭并显示错误消息
Unsupported value: <FlutterError: 0x1c422d200> of type FlutterErrorLost connection to device.
这是我的颤栗医生。

最佳答案

您忘记了MaterialApp中的initialRoute参数
正确的方法是：

return new MaterialApp(
       initialRoute: '/',
       routes: {
        "/": (_) => new WebviewScaffold(
              url: "https://www.paypal.com/",
              appBar: new AppBar(
                title: new Text(
                  "Payment",
                ),
              ),
            )
        },
);
