Answer 1

I am not entirely sure if I understood the problem. But here is what can be done.

1. Open url in webview.
2. Now you should listen to webview state change. There must be a listener for this. say the listener is webViewStateChanged which will give you the state of webview.

Then you can check like

  void webViewStateChanged(WebViewStateChanged newState) async {
    if (newState.type != WebViewState.finishLoad ||
        newState.url != desiredURL) {
      return;
    }

    // At this point, you want to return to your app. If you need data from 
    // website, you can do so by accessing cookies of webview. 

    // Now you are back to the app, you can pop/replace the webview whatever
    // is your requirement.
