CustomDotIndicator class

A custom dot indicator for showing progress through multiple steps.

This widget is commonly used in onboarding screens or step-based wizards to indicate the current step or page. It displays a row of dots, with the active dot styled differently from the inactive ones.

currentIndex specifies the current active step. totalDots is the total number of steps or pages. activeSize and inactiveSize define the size of the dots.
