Should I add a Laravel provider directory to .gitignore or not?

Question

I have a vendor directory in a file .gitignore. Every time I run composer update, git cannot keep track of updates and directory changes vendor, and therefore I cannot undo those changes!

My question is: Is it possible that the application crashes or errors occur after composer update, so there is a need for it git reset?

If possible, is it better to delete the vendor directory from .gitignore? maybe there are other solutions to this problem? (if at all a problem !!)
