在具有附加权限的调试控制台中获取与剪贴板数据相关的警告错误

Question

我一直在从事一个涉及ESP32蓝牙和Flutter应用程序的项目。大约一周前，我的应用程序工作正常，没有这些警告消息，我在外面呆了一段时间，无法使用它，当我回来时，遇到了这条消息。该应用程序似乎工作正常，但每当我点击或单击某些内容时，我都会收到此“警告”消息。

如果我在 IOS 模拟器中运行该应用程序，它会正常工作而不会出现此错误，但在我的 Android 设备上运行时，会出现该错误。

这是我不断收到的消息：

我尝试将其添加到我的 Android 清单中，但没有成功：

这可能与剪贴板缓冲区中存在图像有关。

我遇到了同样的问题，当我将一些文本复制到手机上的剪贴板中时，调试消息就消失了。
