我正在使用 Flutter Driver 为使用 CoachMark 库的应用程序编写集成测试（https://pub.dev/packages/tutorial_coach_mark）
我想单击文本以关闭 CoachMark，但是当我尝试使用 VSCode 的小部件检查器检查它时，文本没有显示在小部件树上，当我将检查器悬停在该文本上时，它指向MaterialApp根小部件（见截图）
这些是我试图找到它们但没有运气的方法：
find.byType('Text')find.text('OKE')find.byType('RichText')- 甚至这个嵌套的、令人困惑的查找器
return find.descendant(of: find.byType('Align'), matching: find.descendant(of:find.byType('SafeArea'), matching: find.descendant(of:find.byType('AnimatedOpacity'), matching: find.descendant(of:find.byType('InkWell'), matching: find.descendant(of: find.byType('Padding'),matching: find.text('OKE'))))));
我尝试使用第 4 种方法的原因是当我尝试深入了解库代码本身时，它会构建类似这样的小部件
Widget _buildSkip() {
if (widget.hideSkip) {
return SizedBox.shrink();
}
return Align(
alignment: widget.alignSkip,
child: SafeArea(
child: AnimatedOpacity(
opacity: showContent ? 1 : 0,
duration: Duration(milliseconds: 300),
child: InkWell(
onTap: widget.clickSkip,
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Text(
widget.textSkip,
style: widget.textStyleSkip
),
),
),
),
),
);
}
我又附上了一张截图来显示我想要点击的内容（屏幕右下角的文字）
有什么建议吗？

<br？这是构建小部件的代码：

是因为 Coach Mark 库创建了全屏覆盖之类的东西，所以我无法识别小部件吗？如果是这样，我该怎么办？
