Flowchecks were popular in WWII, but are generally considered a little too vulnerable to memory and attention lapses in modern airliners. Airliners these days usually use challenge-response checklists where the PM (pilot monitoring) calls out checklist items and the PF (pilot flying) touches the switch or control and responds with the setting. On a checklist it looks something like: flaps .. set fms .. set EPR .. set v1 .. 80 knots (below - abort for any emergency, above - abort only for those things that you really can't take into the air). v2 .. 120 knots runway .. 28L. Compass and HSI match with runway numbers. We are on the left runway. takeoff clearance .. cleared for takeoff. My controls (PM says "your controls", PF repeats "my controls). And so on.
