Widget to display dots indicator to show a position (for a PageView for example).
You just need to add
dots_indicator as a dependency in your pubspec.yaml file.
dependencies: dots_indicator: ^0.0.5
In these example,
pageLength is the total of dots to display and
currentIndexPage is the position to hightlight (the active dot).
new DotsIndicator( dotsCount: pageLength, position: currentIndexPage )
new DotsIndicator( dotsCount: pageLength, position: currentIndexPage, decorator: DotsDecorator( color: Colors.black87, activeColor: Colors.redAccent, ), )
You can change the default size of dots.
So you can choose to have dots for no active positions and a rounded rectangle for active position for example.
By default, the shape of dots is CircleBorder, so to have a rounded rectangle for active, you need to change
new DotsIndicator( dotsCount: pageLength, position: currentIndexPage, decorator: DotsDecorator( size: const Size.square(9.0), activeSize: const Size(18.0, 9.0), activeShape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0)), ), )
You can change the default shape of dots. By default it's a CircleBorder.
You can change the no active and active dot shape.
new DotsIndicator( dotsCount: pageLength, position: currentIndexPage, decorator: DotsDecorator( shape: const Border(), activeShape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0)), ), )
By default a dot have a margin of 6 pixels on his left and right. It's
But if you want you can change it, for example to increase the space between dots or to add top margin.
new DotsIndicator( dotsCount: pageLength, position: currentIndexPage, decorator: DotsDecorator( spacing: const EdgeInsets.all(10.0), ), )
Add this to your package's pubspec.yaml file:
dependencies: dots_indicator: ^0.0.5+1
