不能运行在物理设备或模拟器上运行 flutter 应用程序

Question

我一直在尝试运行物理设备上的一些基本 flutter 代码（几天前工作）我对 flutter 有点陌生，但留下了这条错误消息。无效的 depfile：/mnt/2d3f0752-b6d9-49f5-94cc-f85e942a8495/home/abdullah/UIA/212/MAD/mad_assignment/.dart_tool/flutter_build/10a98dcd0759222e9209b6893a2ed34e/kernel_snapshot.d ：错误：未找到：'dart:html' lib/home.飞镖:1 导入 'dart:html';
