Dark energy are mysterious and still remain unknown. Here we investigated the parameters of hubble constant and dark energy by fast radio bursts (FRBs) which are new emerging transient in the universe. However, redshift of FRBs still need to identify counterpart. Adopting the detection ability of Square Kilometre Array, we generated the FRBs data using Luminosity-duration relation (Hashimoto relation) and propose the cross-correlation method between spatial distribution of the galaxies data with known redshift and the FRBs without redshift measurement. Moreover, we discussed two population of FRBs: repeating and non-repeating FRBs in the mock data. We show that once we measure the observed fluence and intrinsic duration of FRBs, the dark energy can therefore be constrained.
