我正在创建flutter应用的集成测试，但在查找TextInput并尝试在其中键入内容时遇到此错误。'package:flutter_test/src/binding.dart': Failed assertion: line 1649 pos 12: '_pendingFrame == null': is not true.
代码：

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, "teste@teste.teste");

我没有在互联网上找到这个错误是什么。
以前有没有人遇到过这个异常，并且知道如何解决它？
