Question

我制作了一个使用AlertDialog的小部件（GirafNotifyDialog）。该小部件由一些文本和一个按钮组成，单击该按钮可关闭对话框。在测试窗口小部件时，我尝试确认按下按钮后窗口小部件消失了，但是测试仍然失败，并且我尝试了其他几种方法，但是似乎都没有用。这个问题的代码可以在这个github问题上看到： https://github.com/flutter/flutter/issues/30372

对于能够测试该小部件从屏幕上消失的任何帮助，深表感谢！

按下和点击按钮似乎没有什么区别。我试图测试该小部件是否仍然可见，即使在按下按钮后也是如此。

测试

void main() {
  GirafNotifyDialog dialog = GirafNotifyDialog(
      title: 'TestingTitle',
      description: 'This description is for testing',
  );
  const String okayBtnKey = 'NotifyDialogOkayButton';

  testWidgets('Notify dialog pops on confirmation',
          (WidgetTester tester) async {
    await tester.pumpWidget(
      MaterialApp(
        home: dialog,
      )
    );
    await tester.pump(Duration(milliseconds: 500));
    await tester.press(find.byKey(const Key(okayBtnKey)));
    await tester.pump(Duration(milliseconds: 500));
    expect(find.byType(GirafNotifyDialog), findsNothing);
  });
}

和按钮

RaisedButton(
                  key: const Key('NotifyDialogOkayButton'),
                    shape: RoundedRectangleBorder(
                        borderRadius: BorderRadius.circular(10.0),
                        side: const BorderSide(
                            color: Color.fromRGBO(0, 0, 0, 0.3))),
                    color: const Color.fromRGBO(255, 157, 0, 1),
                    child: Row(
                      children: const <Widget>[
                        Icon(
                          Icons.check,
                          color: Color.fromRGBO(0, 0, 0, 1),
                        ),
                        Text(
                          'Okay',
                          style: TextStyle(color: Colors.white),
                        ),
                      ],
                    ),
                    onPressed: () {
                      Navigator.pop(context);
                    }),

预期结果是该窗口小部件不再可见，但是随着抖动测试响应状态的出现，即使在窗口小部件“应该”消失之后，窗口小部件显然仍然仍然可见。

颤振测试响应：
