@gonuit Is there any problem with this fix? or why don't you just approve it?

The following assertion was thrown while dispatching notifications for IndicatorController:
Build scheduled during frame.

While the widget tree was being built, laid out, and painted, a new frame was scheduled to rebuild the widget tree.

This might be because setState() was called from a layout or paint callback. If a change is needed to the widget tree, it should be applied as the tree is being built. Scheduling a change for the subsequent frame instead results in an interface that lags behind by one frame. If this was done to make your build dependent on a size measured at layout time, consider using a LayoutBuilder, CustomSingleChildLayout, or CustomMultiChildLayout. If, on the other hand, the one frame delay is the desired effect, for example because this is an animation, consider scheduling the frame in a post-frame callback using SchedulerBinding.addPostFrameCallback or using an AnimationController to trigger the animation.

Hi, @Jordan1122 and @ziqq -- sorry for the long waiting time − I'm already working on it ⏲️

[RBT22]

Thank you very much! 🤗

[gonuit]

Version 1.1.2 is available on the pub.dev 💪🏻 and ready for your tests 🕵🏻

[ziqq]

Fix it plz

This problem is caused by #30. Updating the compatibility to 3.0.0 this way comes with losing older versions...

This is a good example of the correct approach:
