parabola Scroll Easing
fun parabolaScrollEasing(currentOffset: Float, newOffset: Float, p: Float = 25.0f, density: Float = 4.0f): Float
A parabolic rolling easing curve.
When rolling in the same direction, the farther away from 0, the greater the "resistance"; the closer to 0, the smaller the "resistance";
No drag effect is applied when the scrolling direction is opposite to the currently existing overscroll offset
Note: when p = 50f, its performance should be consistent with iOS
Parameters
current Offset
Offset value currently out of bounds
new Offset
The offset of the new scroll
p
Key parameters for parabolic curve calculation
density
Without this param, the unit of offset is pixels, so we need this variable to have the same expectations on different devices.
