02/27/2021, 4:27 PMHi guys, how to send data class as an arguments instead of each type in the data class?
P.S -> I'm having list of items in home screen when onClick I need to pass the data as a class!

02/27/2021, 6:42 PMIt is very questionable. This implies that you have persistent storage. But you may not need one, and perhaps navigation should not be the only reason of introducing one. E.g. the app may be fully online (like Uber Eats). Ability to pass objects between screens may dramatically improve UX. E.g. when you open a restaurant menu cart, server may send fully detailed items. So you don't need additional requests when opening specific items from the menu.

02/27/2021, 6:48 PMYes, it is still fine to pass a few thouand bytes. Anyway, glad there will always be ways to use parcelable.
