Since reluctance is equal to length decided by product of permeability and area of cross section,how does reluctance change with flux?

Length divided by product of permeability and area of cross section

Sorry for the inconvenience

It's okay, you're pretty new here.

You already know the answer.
Length and cross section are not dependent on flux (excepting maybe magnetorestriction in iron)

that leaves permeability
which for free space is a constant
and
as that Wiki article explains for most other materials is very near the same constant
the big exception being ferromagnetic materials
which have the classic BH saturation curve.
