Direzione di ricerca
The issue requests adding AutoFitText properties to the Label control. Review the linked Xamarin.Forms PR (#7981) for a prior implementation attempt. The implementation involves creating an AutoFitTextMode enum and two double properties (MaxAutoFitSize, MinAutoFitSize) as BindableProperties, then modifying the Label's layout logic to compute font size based on available width. Key files to examine are Label.cs, possibly LabelHandler or platform specific renderers. Testing should cover iOS, Android, and Windows platforms.
