Narrative:

We received a change of runway and ATIS change during pushback following engine start of number 2 engine. Single engine taxi was planned and information was briefed and changed in the performance computer and the CDU after engine start; but before the before taxi checklist was called. After making all the changes to the performance computer and CDU reviews were made; numbers and flap settings were still the same. I missed calling for the checklist and when as we switched from ramp control to ground control for taxi instructions; we immediately saw that the flaps were not set for takeoff.
