升级flutter后命令不起作用

由于最小v1.5 sdk插件需要，我使用flutter upgrade，但由于我无法使用命令......我找不到bash命令，

我尝试手动下载 1.5 sdk 并替换以前的文件夹，当我使用 flutter doctor 他说我有 1.2.1 ...我尝试重新升级但出现此错误：

Your flutter checkout has local changes that would be erased by upgrading. If you want to keep these changes, it is
recommended that you stash them via "git stash" or else commit the changes to a local branch. If it is okay to remove
local changes, then re-run this command with --force.
