flutter - 在具有附加权限的情况下在与剪贴板数据相关的调试控制台中获取警告错误

Question

我一直在做一个涉及 ESP32 蓝牙和 Flutter 应用的项目。大约一周前，我的应用程序在没有这些警告消息的情况下运行良好，我在外面呆了一段时间，无法处理它，当我回来时，遇到了这条消息。该应用程序似乎运行良好，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，它可以正常运行而不会出现此错误，但在我的 android 设备上运行时，该错误就会出现。

这是我不断收到的信息:

我尝试将其添加到我的 Android list 中，但没有成功:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.project">
         <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
         <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

<application
        android:requestLegacyExternalStorage="true">

这可能与剪贴板缓冲区中有图像有关。

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时，调试消息就消失了。
