title: I can't target the Google Login for integration testing
body: <p>Currently I'm trying to build out the integration testing for an app that someone else built.  I'm stuck with the Google sign in.</p>
  <p>Specifically, the integration testing can't find the Google pop-up page.</p>
  <p>Is there any way to use integration testing for the Google sign?</p>
  <p>If not, how do I use integration to start on any page I choose for testing?</p>
  <p>Please note that I have not built the app; I'm here to test the app.</p>
  <p>I've tried to find a page or anything in the files and folders for the pop-up but I can't find anything.</p>
  <p>I've even tried using Dart DevTools but I still can't target the sign-in page.</p>
  <p>At the very least, can I bypass this step and start the integration on a different page?</p>
  <p>Below is a picture of the sign-in page I'm trying to get the Flutter Integration test to interact with.  Note that it has been modified for privacy reasons.</p>
