我遇到了同样的问题，我检查了内存状态，是的，这种情况发生是因为设备的内存 RAM 已满并自动关闭任务，所以。

我在flutter的observatory中查看状态内存，在应用程序运行时按“Ctrl + Shift + P”并写入observatory查看设备的内存状态enter image description here enter image description here

我用 Image.file 小部件的属性定义了 cacheHeight 和 cacheWidth ，并且我修改了 filterQuality 属性:

Image.file(File(path),filterQuality: FilterQuality.none,cacheHeight: 66,cacheWidth: 50,)

对不起我的英语。
