2 ways :
1-character controller :
if you are using this component you can get this in code and its have a bool named (IsGrounded) and this return the object hit ground or not.
2-collision :
create a bool
in OncollisionEnter set bool to true
in OncollisionExit set bool to false
in OncollisionStay set bool to true
