I Try To use some Hacks Like serliaze the List to Json then in ViewHandler I deserilaze it and it really done the job until We get Best Solution form your side.

Usually it involves wrapping the object in delegate using AttributeValueHolderFactory (and unwrapping it in Handler).

Yes, that's the idea ,so I think jsonize any Generic like list or Ienuramble to be string then de serilasize it from string to Generic is it the good wrapper or do u think it have another best wrapper for it.

Dreamescaper commented 3 years ago

You simply use AttributeHelper.ObjectToDelegate (which uses AttributeValueHolderFactory underneath) in component, and AttributeHelper.DelegateToObject<List<Xamarin.Forms.Map.Pin>> in handler. No need to serialize those. See examples below (from InputView).

Component example Handler example
