With proper descent planning, you can fly the whole approach without flaps, all the while slowing airspeed by reducing throttle and maintaining level flight. The aircraft will naturally reduce airspeed as drag gradually overcomes thrust. Flaps increase lift produced by the wing increasing the angle of attack of the wing, this is also why your stall speed increases with each knotch of flaps. Your FMS will calculate the apppropriate approach speed depending on which flap setting you wish to use.
If you look on a traditional airspeed indicator, you'll see that the bottom of the white arc (stall speed in the landing configuration) is LOWER than the bottom of the green arc (stall speed in the cruise configuration).
It is not true that the stall speed increases with the addition of flaps.
