Narrative:

We were cleared for a visual to 31L off a right downwind. Preceding aircraft reported a very near miss with a drone at 500 AGL on 31L. We were intently looking for the drone. First error was lining up on 31R. Tower queried us about our alignment at four miles and we sidestepped to 31L. We continued to configure while looking for the drone. I called for flaps 30. Pm set flaps 25. We were both outside looking for the drone below 1000 ft. 'Too low flaps' alert. We configured flaps 30 and landed.
