A plane
There is no real world flat surface which goes on forever. It is a geometric idealised concept. So, since there is not even a first such thing, there cannot be another.

The flat surface that goes on and on in all directions has no boundaries. This flat surface is called infinite surface. Accordingly, the answer is that the flat surface that goes on and on in all directions is called an infinite surface.

It is a plane.
There is no real world flat surface which goes on forever. It is a geometric idealised concept. So, since there is not even a first such thing, there cannot be another.
A plane could be considered an endless flat surface. A plane goes out infinitely in all directions, therefore, creating an endless flat surface.
You are probably looking for the word 'plane'.

a line a ray goes in only one direction forever No, a line goes on forever in two directions, a ray starts at one point and then goes on forever.
A flat surface, like a sheet of paper, with no edges (ie: it goes on and on and on and on....) or boundaries. What you're describing is a 2 dimensional plane. No, not plane like an airplane. A plane is simply a flat "sheet" that goes on forever in 2 dimensions: left/right (wide) and up/down (tall).
