Hi,

Really like this lib, but people should be careful when using it in list. I spent a lot of time trying to figure out what was impacting my performance, and never thought of this package.

Did you have other feedback like this ? Could you look into it ?

Regards

Yeah I just noticed that too. I think the Cliper class is cpu intensive since it rebuilds the tree on canvas at a certain rate per second to maintain its look. If you have more than one of this widget, that's additional instance rebuilding that widget at fps.

please, what is the workaround of this, or how where you able to rectify your performance issue @bounty1342 @eyoeldefare

I have the same problem. I have a listview of rated items and it's unusably bad for performance. However, despite just having been featured by google, this lib appears to have been abandoned by the developer.
