Flutter pushes the picker's whole state on every rebuild, and each push reloaded every visible row with fresh, unreused cells. Drop identical states, apply the rest as a diffable snapshot that redraws only changed rows in reused cells, and animate a member's row moving between the chosen and result sections when it is picked or removed.
