deltaFactor property

double deltaFactor
final

A factor that determines the speed at which the child widget's visibility changes when scrolling occurs.

The deltaFactor value should be a double between 0.0 and 1.0, where:

  • 0.0 indicates that the child widget's visibility won't change when scrolling.
  • 1.0 indicates that the child widget's visibility will change rapidly when scrolling.

A lower deltaFactor value results in a slower change in visibility, making the child widget's hiding/revealing behavior more gradual. Conversely, a higher value makes the change in visibility more immediate.

The default value is 0.04, which provides a moderate speed of visibility change.

Implementation
