And because uuid >=3.0.0 depends on crypto ^3.0.0, cached_network_image >=3.0.0 requires crypto ^3.0.0. And because every version of json_model depends on build >=1.0.0 <1.2.0 which depends on crypto >=0.9.2 <3.0.0, cached_network_image >=3.0.0 is incompatible with json_model. So, because groupbuy depends on both cached_network_image ^3.0.0 and json_model any, version solving failed. pub get failed (1; So, because groupbuy depends on both cached_network_image ^3.0.0 and json_model any, version solving failed.) exit code 1
