What does 'ever' mean here? And how to use this word?

"Ever" is an adverb meaning at at any time, at all times, or always. It is used in conjunction with a verb to modify (or describe) it. You can use it in negatives, but it is more common to use "never" in such contexts. Ex. I won't ever eat meat again, I'm turning vegan. Ex. I have not ever eaten fish in my life. -> I have never eaten fish in my life.
