To me it makes sense that both 'dotCount' and 'position' should be int ('dotCount' is the number of dots, and 'position' is the index of the current dot). Why is 'position' a double? What does it mean for position to be 1.5?
The library 'package:dots_indicator/dots_indicator.dart' is legacy, and should not be imported into a null safe library.
Try migrating the imported library.

How to make an indefinite indicator like https://github.com/wching/Android-Indefinite-Pager-Indicator with this library ?
Hi,
I am getting error as:
'package:dots_indicator/src/dots_indicator.dart': Failed assertion: line 31 pos 16: 'dotsCount != null && dotsCount > 0': is not true.
In init state part I am getting a data from remote server. Once the data verify I set the loadIndicator true so I can show the page. in area that data verify before setting the page loadIndicator to true in setState I set the pageLength. pageLength is integer and it totals of list of the data that I get from database. Everything works. Even I set the dotsCount = pageLength;
Any idea why I am keep getting this error?

Hey Thanks for the awesome package. This made my job very easy. However the direction property is missing. I would like to use a vertical indicator rather horizontal. Do you have plans to upgrade the plugin anytime soon?
Latest change (position to int) is a breaking change and as such can break other (library) packages which depend on dots_inidicator.
Would it be possible to pull the latest version and re-release it as a breaking change (3.0.0)?
Hi there ! Just wondering if there is functionality to change the color of the inactive dots. I did not see it explicitly and it's very possible I overlooked something!
Letting you know because, we don't like to use same color code again and again.
Hi! Great library, thanks for writing it.
I wrote a wrapper to integrate these indicators with flutter's built-in PageController
. I'm posting it here in case it's a useful addition. Feel free to assign me a PR if this should be integrated with DotsIndicator, or close this ticket if it's out of scope.
What this does:
PageController.addListener
so it receives updatesDotsIndicator.onTap
to the PageController so taps update the PageView positionclass ListenerDots extends StatefulWidget {
final PageController pos;
final int dotsCount;
const ListenerDots({Key? key, required this.pos, required this.dotsCount})
: super(key: key);
@override
State<StatefulWidget> createState() => _ListenerDotsState();
}
class _ListenerDotsState extends State<ListenerDots> {
double lastPos = 0;
@override
void initState() {
widget.pos.addListener(updatePage);
super.initState();
}
/// listen handler
updatePage() => setState(() {
lastPos = widget.pos.page ?? 0.0;
});
@override
void dispose() {
widget.pos.removeListener(updatePage);
super.dispose();
}
onTap(double offset) {
widget.pos.animateToPage(
offset.toInt(),
duration: const Duration(milliseconds: 200),
curve: Curves.easeInOut,
);
}
@override
Widget build(BuildContext context) => DotsIndicator(
dotsCount: widget.dotsCount, position: lastPos, onTap: onTap);
}
It seems the widget is taking all page width and is left centered.
How to center this DotIndicator widget ?
The plugin is working perfectly for the mobile app (Android / iOS)
When I try to use this plugin with flutter web it works fine except when I try to resize the window.
When I resize the window, more points are added to the dots indicator and an overflow appear on the right.
Error:
The relevant error-causing widget was:
Row org-dartlang-app:///packages/dots_indicator/src/dots_indicator.dart:61:11
The overflowing RenderFlex has an orientation of Axis.horizontal.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.
Hi,
I noticed that ColorLoader
is not well centered. Reason is that only the right padding is added in the _ColorLoaderState
build
function, so dots are shifted left as a result.
It can be fixed if padding for dots is set in following order:
padding: const EdgeInsets.only(left: 4.0, right: 8.0)
padding: const EdgeInsets.only(right: 8.0)
padding: const EdgeInsets.only(right: 4.0)
I guess since it is a small fix I post it here..but if you want I can send a pull request too.
Cheers,
Milos
I have a Pageview widget setup along with dots indicator. When the page changes the "position" of the dot also changes. So the dot transition happens immediately even before the page transition completes. A "delay" property would be great to keep both dot and the page transitions in sync.
