Wouldn't it be better to stick with the original "peekHeight" and "maxHeight"?
Same applies to

My intention was to abstract the
BottomSheetBehaviorproperties away as much as possible, becausepeekHeightis not the "first detent heightandmaxHeightis notsecondHeight` in general. They serve these functions only when other properties are set appropriately.I've yet failed to abstract it away from useThreeDetents, because situation is a little bit more complicated there & requires another refactor, which will come in the future.
