This is straightforward in finite volume method. The flux on a wall face will involve only terms containing the wall normal temperature gradient

-k dT/dn

which you can replace with the prescribed flux.

if this ur code then make -k dT/dX = Q(const) in fourieers and solve to get CI and PI, resultant eqn will represent such a boundary condition.
