dynamicSizeEquation property

(double Function(double distance)?) dynamicSizeEquation

Custom equation to determine dynamic item scaling calculation

Input parameter is distance between item position and center of ScrollSnapList (Negative for left side, positive for right side)

Output value is scale size (must be >=0, 1 is normal-size)

Need to set dynamicItemSize to true

Implementation

final double Function(double distance)? dynamicSizeEquation;
