Reddit: Can anyone summarize the difference between popular Flutter architectures?
I have been trying to look around quite a lot but I haven't been able to find a nice summary of all the more widely discussed patterns together. Can anyone summarize Scoped Model, BLoC and Redux in a few words? Comparison with traditional MV* patterns will help a lot too!

Reddit: Isn't the idea of rebuilding widgets with Redux terribly wasteful?
I just started writing a Flutter app with Redux with no previous background in React or Redux. I come from Android, Windows desktop and embedded development and one thing that is getting to me is the constant rebuilding of widgets. Looking at the plethora of Todo app examples, I see them rebuild the whole widget tree top down every time an item is added or removed. Just the functional aspect of rebuilding a List to add an item scared me a bit.Isn't all this terribly inefficient? Am I doing something wrong? Intuitively, if I change some text in a list I shouldn't be rebuilding my UI from top down.

Reddit: A few questions about adopting Flutter.
I have an iOS and Android app that use bluetooth and save a lot of data points on a Realm database locally. How does Flutter do running in the background with both platforms? I know Realm is not available for Flutter but could I build an extension on Android and iOS to read and write to it? Would that be too slow? What types of functions should or should not be handled by the native framework instead of Flutter? Thanks guys!
