Using provider package StreamProvider with declarative UI
Hi guys, I've been trying to wrap my head around data flow and state management in flutter particularly using the provider package. I tried querying from firestore using Futures but turns out that doesn't fully utilise the capabilities of firestore. So I switched to using Streams instead, and using StreamProvider to get the data. Problem is I can't figure out at what point/how to tell the UI to rebuild.. sometimes the stream shows data, sometimes it doesn't and I can't really tell what's going on during those times. Say I wanted to show a circular progress bar when the view is busy, how do I achieve that when using StreamProvider. Does it even make sense to do that?

Is it okay to store application state inside a BLoC?
Can I put app state (like a list of objects) inside of a BLoC as a variable, or should the data be stored somewhere else?

Where are the jobs?
I just started learning Flutter after being frustrated with Xamarin at work- I absolutely love this framework. It's easy, straight forward, and makes sense.I took a look online to see if there were any jobs near me (I'm in Atlanta), and there are none... are you guys doing this as a hobby, or are the jobs only out in silicon valley?

Change my mind - Flutter sucks and Dart suffers from scope-nesting hell.
(Disclaimer - I used Angular1, and then witnessed Google release 10 different versions of the same mentally impaired framework, each one featuring more cargocult bullshit than the last. I am not confident in Google's leadership or ability to ship a framework.) Now imagine you're working on an App, and you implement the designs according to the wireframes, but whoops, they've changed all the design specifications and your UI code is a bundled together and a self-referential mess because that's how Flutter+Dart works by design. Why the hell would I want to do this to myself?
