使用Patrol做集成测试时，Pinput组件enterText()方法失效求助

在使用Patrol执行Flutter集成测试时，发现enterText()方法无法对Pinput组件正常输入内容。以下是测试用例代码：

final TextEditingController controller = TextEditingController();
const length = 4;
final focusNode = FocusNode();
final ref = ProviderContainer();

await $.pumpWidget(
  UncontrolledProviderScope(
    container: ref,
    child: MaterialApp(
      home: Scaffold(
        body: Pinput(
          autofocus: true,
          controller: controller,
          focusNode: focusNode,
        ),
      ),
    ),
  ),
);
focusNode.requestFocus();
await $.pump();
const pinValue = '1234';
await $.tester.enterText(find.byType(Pinput), pinValue);
await $.tester.testTextInput.receiveAction(TextInputAction.done);
await $.tester.pumpAndSettle();

测试输出显示输入未被Pinput组件正确接收，组件未填充预期的"1234"内容。该问题已提交至Pinput的GitHub仓库issue #140，寻求解决方法。
