Human Factors
After starting engines and receiving the salute there was an issue with the temperature in the FMC (Flight Management Computer) dropping out causing auto throttle to trip off. F/O (First Officer) reloaded performance data and we armed the auto throttle. I then called 'after start checklist' without calling 'set flaps 1; after start checklist '. I noticed during taxi and before the before takeoff checklist that flaps were not set and I called for flaps to be set to 1 and we discussed what happened and how we became distracted. Everything proceeded normally after that.
Flight Crew flying 737 aircraft missed 'Set Flaps 1' callout after pushback.
