feedbackScaleFactor property
The scale factor applied to the feedback widget during a drag operation.
This determines how much the feedback widget (the visual representation of the widget being dragged) will grow or shrink when the drag starts. A value of 1.0 means no scaling, while a value greater than 1.0 enlarges the feedback widget. For example, a value of 1.5 will increase the size by 50%.
Default value: 1.05 (feedback widget grows by 5%)
Implementation
final double feedbackScaleFactor;
