Friendly reminder for all Bloc users: always return only unmodifiable lists.
Just finished my 2 day debug session with the help of a very friendly flutter expert. It was caused by streaming a modifiable List from a bloc. In some widget some items were removed from the list which in turn also removed the content in another place - which you obviously don't expect.So kids, always use an unmodifiable List or a library like kt.dart when exposing any List from a bloc.Funny thing is that I was already developing the app where this happend since a year and in the whole time using Bloc this error never happend to me once. Well at least I learned my lesson now😉.

Flutter commands hang in vscode
Hello everyone,I'm trying to use flutter in vscode but none of the commands will work. Trying to run flutter doctor, new project, run or any other suggested commands from the drop down menu just results in a "running..." message in the notification menu that seems to last forever. Any tips for a confused newbie flutterer?Edit: I've already tried reinstalling vscode and both the flutter and dart extensions as well as running vscode as admin and adding flutter to path

Restrict API keys (Google services etc.)
Hey.​Im building an app which rely on google maps services. I have worked around this problem for a long time now but with static maps api Im stuck now.​So to do request from the app you need to authorize the HTTP request with a API key in the end of the query like: www.maps.google.com?QUERY&key=THE\_API _KEY​I dont want this key to be public visible because someone can steal it and use my quota. I can't be the only one faceing this problem? I have worked around it with other services by doing the request from the server side. But here i really dont want to serve static images from my backend server.​Do someone have a suggestion how to solve it? or someone in the same situation as me? Please tell me if you need more information to solve the problem.

How to repaint from outside main.dart?
I wanted to outsource some code to different dart-files, so I created some static classes that create widgets of some kind for me. However, if I need to repaint nothing happens, because (I guess) setState isn't called. How would I need to change my code to repaint? main.dart for example return

Does Firebase Documentation for Dart/Flutter Exist?
Hello all!Does anyone know if there is any official Firebase documentation for Dart/Flutter (Specifically Cloud Firestore) available? I couldn’t find anything on the Firebase website, but I find it hard to image that Google wouldn’t be updating their official documentation to support one of their homegrown products.

How to show a circular spinner on login page.
Could some of the brilliant minds on here kindly help a noob with regards to a simple Flutter dilemma.I am trying to create a simple login page which does an authentication on button click using the BLOC
architecture pattern.I have most of the piece working except one thing:How do I display a CircularProgressIndicator
in the center of the app while the login is in progress and then dismiss it once it's complete (irrespective if the call is a success or failure)?I am seeing conflicting answers where some are recommending usage of Streams, Future or FutureBuilderP.S: Posted same question on SO: https://stackoverflow.com/questions/57063225/flutter-show-spinner-on-loginThanks!
