The new Flutter Framework

Also a few suggestions for stacked package 1. when using viemModelBuilder with onModelReady for a screen, for any exceptions that are caused from the database or if there are no objects in the database i am sending them as custom objects, it would be better if there is a more efficient way. 2.

@@srineeshsalur524 Thanks for sharing that resource. No, that's not correct. You register all services in the same file. 1. I don't know what that means exactly. We're providing a function for you to run code when the model is ready, there's nothing else that function is meant for. Error handling is up to you, I can make it opinionated but at the moment it's not a high priority. 2. I show that in some of the videos i think. When I get something from say getPosts I first check locally if I have the results. If I don't then I go to the api. When the results come back from the api then I save it locally. If that same set is requested next time then it'll be on disk so will return quick. It's all done service side, the viewmodel stays the same.
