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.
This package is not upload to Pub yet. So you need to add it from Git repository:
dependencies: dots_indicator: ^0.0.3
In these example,
pageLength is the total of dots to display and
currentIndexPage is the position to hightlight (the active dot).
A simple dots indicator #
new DotsIndicator( numberOfDot: pageLength, position: currentIndexPage )
Custom colors #
new DotsIndicator( numberOfDot: pageLength, position: currentIndexPage, dotColor: Colors.black87, dotActiveColor: Colors.redAccent )
Custom size #
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 dotActiveShape
new DotsIndicator( numberOfDot: pageLength, position: currentIndexPage, dotSize: const Size.square(9.0), dotActiveSize: const Size(18.0, 9.0), dotActiveShape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0)) )
Custom shape #
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( numberOfDot: pageLength, position: currentIndexPage, dotShape: const Border(), dotActiveShape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(5.0)) )
Change the space between dots #
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( numberOfDot: pageLength, position: currentIndexPage, dotSpacing: const EdgeInsets.all(10.0) )
