Call for assistance: macos_ui package
Hi everyone.In light of discussions I've had on Twitter about the lack of a macOS style widget/theme pack, I've started a package for this: https://github.com/GroovinChip/macos_ui. This is a huge undertaking so I'd appreciate any assistance, be it advice, feedback, repo maintenance, code contributions, or simply spreading the word.Thanks!

Would anyone like to share their portfolio site made using flutter web?
Hi, I am an app developer. I have been using flutter for a long time now. Since flutter web is in stable channel now, I am thinking of creating my portfolio site using flutter only owing to it's amazing UI capabilities. Let me know if anyone else has done that. If you haven't created it using flutter, I would still like to look at it and may be recreate it in my own way using flutter :)

Getting Bool State from Firestore in Dart
Hello! I am trying to get a bool value from Firestore when the app is being initialized/reloaded: it returns True if it is "like" and False if it is not "like". Every time a user likes/unlikes a post, a database (called userFavorites) is being created or update on Firestore. So when initializing/reloading the app, I'm trying to get access to this True/False for each of the posts that are being displayed on the UI (if the user has never liked or unliked the post, the value for this bool will automatically be False). The problem that I am having is that I am not able to get and display the T/F bool value from the Firestore database into the UI each time a post is reloaded (or seen on the screen). What code could I use to do that? Thanks!

Normalized state in Bloc Flutter
Like everyone, I am also confused about statemanagement in Flutter, but I really like Bloc and the library. But one thing is not clear. I read all the docs and all the tutorials already.I come from redux where you have one big global store, in which you have normalized states. I don't know if I should or how I should correlate redux to bloc, but they felt similar from the beginning and they still do. You have a state, events and you listen to state change and trigger events..Say I have an app where I have posts, I might create, list a post show it in a screen, in another screen etc. I might fetch and cache an post. Doesn't this require me to have a normalized state somewhere? And where?Normalized state is basically having a single place for storing an object, like storing it in a map, and referring to that object in other places by id, then using the map to show the object in the UISo where should I put normalized state in Flutter? In a bloc? In a bloc high up in the tree? In the repository? Should I use normalized state at all or is there another way to think about this? Thank you!
