Usage

SmoothPageIndicator uses the PageController's scroll offset to animate the active dot.

SmoothPageIndicator(  
   controller: controller,  // PageController  
   count:  6,  
   effect:  WormEffect(),  // your preferred effect  
   onDotClicked: (index){  
         
   }  
)

Usage without a PageController

Unlike SmoothPageIndicator , AnimatedSmoothIndicator is self animated and all it needs is the active index.

AnimatedSmoothIndicator(  
   activeIndex: yourActiveIndex,  
   count: 6,  
   effect: WormEffect(),  
)

Customization

You can customize direction, width, height, radius, spacing, paint style, color and more...

SmoothPageIndicator(  
   controller: controller,  
   count:  6,  
   axisDirection: Axis.vertical,  
   effect:  SlideEffect(  
      spacing:  8.0,  
      radius:  4.0,  
      dotWidth:  24.0,  
      dotHeight:  16.0,  
      paintStyle:  PaintingStyle.stroke,  
      strokeWidth:  1.5,  
      dotColor:  Colors.grey,  
      activeDotColor:  Colors.indigo  
   ),  
)

RTL Support

Smooth page indicator will inherit directionality from its ancestors unless you specify a directionality by passing it directly to the widget or wrapping the Indicator with a Directionality widget from the flutter package.

SmoothPageIndicator(  
   controller: controller,  // PageController  
   count:  6,  
   // forcing the indicator to use a specific direction  
   textDirection: TextDirection.rtl  
   effect:  WormEffect(),  
);
