Flutter integration test failing with error `'_pendingFrame == null': is not true.`

I'm creating an integration test to my flutter app but I get this error when finding an TextInput and trying to type inside. The error: 'package:flutter_test/src/binding.dart': Failed assertion: line 1649 pos 12: '_pendingFrame == null': is not true.

The code:

final Finder email = find.byWidgetPredicate(
      (widget) => widget is FutXTextField && widget.title == 'EMAIL',
    );

expect(email, findsOneWidget,
        reason: " Só pode haver um botão de escrever email");

await tester.enterText(email, "[email protected]");

I didn`t find it anywhere on the internet what this error is.

Does anyone had this exception before and has any idea of how to solve it?

In our case, turned out to be VS Code. Running the test on Intellij IDEs worked flawlessly. I believe running via command line will also work.

I had this error because of an asynchronous method that I used in my test but didn't await.

I had the same error when the app that I was running the test on threw an exception, if you check the logs do you see any errors occurring before your test failed?
