How to make a flashlight for a mobile game?

Hello ppl. Would anybody know how to make something like this:
I know the game in the video is not made with unreal, but is there a way to do something similar with unreal?

I have read all the threads about dynamic lighting for mobile on these forums, but the examples that were given never worked for me.

So if anyone could share a project or make a tutorial, I would donate you money.

4 day bump.

I tried all the ways suggested in this thread:

Can’t get it to work. Idk if I’m missing something or what is it. I tried to contact one of the guys directly with no luck.

So anyways another bump. Maybe someone can help.
