Navigation inside webview with atos payment system

First, thank you very much for this very nice plugin for flutter.

Next, i need your help because i am trying to implement payment system inside flutter_webview_plugin.

When i open the webview for example like this :

```
// close any open browser (happen on hot reload)
await flutterWebviewPlugin.close();
_isOpen = true;

// init server
_server = await _createServer();
_listenCode(_server);

// catch onDestroy event of WebView
flutterWebviewPlugin.onDestroy.first.then((_) {
_close();
});

flutterWebviewPlugin.onBackPressed.first.then((_) {
_close();
});

// launch url inside webview
flutterWebviewPlugin.launch(url,
clearCookies: !cookie, fullScreen: fullscreen);
```

It is working well and my user is redirect to flutter webview to my payment page.
But when i am on the payment page atos ask me to chose my credit card like this :


On the computer when i click on a card everything is working well and i am redirected to the next page but when i am inside the flutter webview nothing happened and the flutter console show :
