Human Factors
On a night visual approach; I called for flaps to 30 at a speed above 165 knots. The Captain stated he would give me flaps 25 because my airspeed was still too fast for flaps 30. As we intercepted the final approach course and went through 1000 ft (pretty much on profile but about 10 knots fast) we made the appropriate calls. The flaps were still at 25. I don't specifically recall doing the Landing Checklist. If we did we clearly blew through checking the flaps because they were still at 25. At about 200 to 300 ft we received the warning 'too low flaps.' We both realized the flaps were at 25 immediately and I called for flaps 30. I continued the approach to landing without further incident. The approach was a bit unusual because we intercepted inside the final approach point. It was enough out of my normal habit pattern to create a distraction that made me feel a bit more task saturated than a normal approach; which I feel lead to the error.

B737 flight crew reported they selected final flaps when the GPWS flap warning sounded on a night visual approach.
