Flutter - 键盘未显示在 Android 12 设备中

Question

对于 Android 12 设备，键盘未显示，覆盖层显示键盘已打开，但未显示任何内容。它适用于较旧的 Android 版本。

\n

键盘在其他应用程序中工作正常，并且在具有 Android 12 以外的 Android 版本的模拟器上也能正常工作。在物理设备上尝试过，Android 12 的 Pixel 也面临同样的问题。

下面是带有键盘的简单文本字段的图像，也尝试更改文本字段的所有属性。它是一个现有的应用程序，因此尝试测试现有的文本字段，即使在那些显示相同行为的文本字段中也是如此。

我认为这个错误是因为这个模拟器与系统UI错误，你可以擦除模拟器的数据然后再次运行
