We investigate the cosmological evolution for the physical parameters in Weylintegrable gravity in a Friedmann--Lema\^{\i}tre--Robertson--Walker universewith zero spatially curvature. For the matter component, we assume that it isan ideal gas, and of the Chaplygin gas. From the Weyl integrable gravity ascalar field is introduced by a geometric approach which provides aninteraction with the matter component. We calculate the stationary points forthe field equations and we study their stability properties. Furthermore, wesolve the inverse problem for the case of an ideal gas and prove that thegravitational field equations can follow from the variation of a Lagrangianfunction. Finally, variational symmetries are applied for the construction ofanalytic and exact solutions.
