Tooltips on trendlines don't work on iOS

Tooltips are NOT invoked when clicking-on/hovering over the two markers (begin/end) of a trendline. This only happens on iOS - works fine on OSX/Chrome/etc. 

I've created a custom builder in tootipBehavior just to see if it gets even called in iOS - answer - NO. Again, gets called (as expected) on OSX/Chrome/etc.

Anyone else found this/know a workaround?

Thanks

iOS 18.2 / syncfusion_flutter_charts: 28.2.5

Hi  Allister,

 

The reported issue has been fixed and rolled out in our weekly patch release on February 25, 2025. So, we kindly request you to upgrade the syncfusion_flutter_charts package to the latest version below. 

 

Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/28.2.7

 

Root cause: The trendline tooltip is handled only on pointer hover, causing it to not appear on mobile devices.

 

Regards,

Baranibharathi P.
