We failed to correctly set flaps for takeoff after a runway changeI was First Officer and Pilot Flying. We were delayed for over an hour for an EDICT time. When we finally left our pushback clearance was changed twice then we were given taxi instructions to 10L. We started taxiing with a hold short clearance and completed the before takeoff checklist to the line but were then given a runway change to 10R along with new taxi instructions and a second hold short clearance. I updated the FMS and I allowed myself to be distracted and forgot to inform the Captain that the new runway required us to change our flap setting. We were told to expect a XA08L departure but immediately after starting the second engine we were given an early position and hold clearance with traffic on final. We completed the before takeoff checklist without repeating the items above the line. We completed a normal takeoff and climb and I only noticed my error when we retracted the flaps. Vls came up faster than normal so I lowered the pitch to ensure we would continue to accelerate. The rest of the climb was uneventful.My biggest error was not asking for more time when I felt rushed to be ready for a position and hold. Other errors were not resetting flap in accordance with the takeoff date for our new runway and not repeating the entire before takeoff checklist.
A320 First Officer reported pre-departure high workload coupled with a runway change that resulted in taking off with an improper flap setting. Once flaps were retracted; the flight proceeded uneventfully.
