How do I implement a fill mechanism in a drawing game
This is an example of what I am trying to achieve. I have got the normal drawing part right using line renderer but unable to figure out how to achieve the fill part. Can someone please help me out with the approach I should take for the fill mechanism.

PS: I am trying to achieve the fill mechanism is a way as shown in the video, not a paint bucket mechanism.
