To recover a dropped stash in Git, you can use the git stash apply command with the --index option and the name of the stash.

For example:
 

git stash apply --index stash@{2}

This will apply the changes in the stash with the name stash@{2} to the current branch and try to preserve the staged changes as much as possible.

If you want to apply the changes in the stash and also remove the stash from the list of stashes, you can use the git stash pop command with the --index option and the name of the stash, like this:
 
git stash pop --index stash@{2}

This will apply the changes in the stash and remove it from the list of stashes.

It only works when the stash exists in your repository. It is not possible for the permanently deleted stash.
