I think that was his point. To calculate if you are going to stall in a final, you need to know your weight and flap setting to see if you will exceed the critical angle of attack when doing the turn, exactly because the speed isn’t constant.

No, you just need an angle of attack sensor. These are increasingly available for small GA planes.

stall AoA depends on flaps though?

Yes, and some sensors do take flaps position into account (or you compromise and have it display the AoA with a typical approach setting).

You need an AoA sensor to see if you are currently stalling or are just about to stall. To predict if you will stall at a specific point in your approach before you’re there, you need to know your weight, too.
