Departed ZZZZ Runway X Center on the SID. During the takeoff briefing I brought it up to the Captain (PF) and briefed the 220 knot restriction at [fix] on the SID.  After takeoff PF called for flaps 1 a few miles prior to the turn during acceleration. I asked to verify that he wanted that. After delaying slightly; I thought we were close enough to the turn that it would not be a problem; and set the flaps to 1. We were at flaps 1 for approximately 30 seconds before the speed bug advanced and we began accelerating again. The PF should not have called for; and I never should have positioned the flap lever out of position 5 until after the turn was complete and we were accelerating again. Additionally; the Relief Officer should have spoken up and brought the error to our attention as well. We thoroughly debriefed the error during cruise and again after the flight. Recency of experience was a contributing factor as all of us had not been flying as much due to COVID-19.
Departing [Runway] X Center ZZZZZ on the SID.  The departure was briefed by the PF with input from the PM at the gate to include that it would be a Flaps 5 T.O. and with the low speed at fix of 220 knots the need to delay flap retraction from 5 to 1 until passing ZZZZZ1 [fix]. After takeoff; climbing out we were accelerating and the PF called for Flaps 1 and the PM raised the flaps from 5 to 1 with a minimum flaps 1 speed of around 230 knots.  When the call was made we were accelerating but we were about 2 miles from the fix with a speed of 220 knots.  The PF had to stop the acceleration at 220 knots (10 knots below flaps 1 speed) for less than 30 sec before he could continue to accelerate to the flaps 1 min speed.
Air carrier flight crew reported a flap configuration problem on departure resulting in a speed deviation. First Officer made reference to lack of flying as a contributing factor.
