file_selector plugin
I've seen that the Flutter team recently posted the file_selector plugin on pub.dev:https://pub.dev/packages/file_selectorIt's basically a cross-platform file picker that works on web, mobile, and desktop. I tried it out but I seem to be just getting errors saying "not implemented", did anyone try it out yet?I did try to look at the source code on GitHub -- https://github.com/flutter/plugins/tree/master/packages/file_selector -- but it seems there's only the Flutter/Dart part, not the iOS/Android/web/desktop stuff, so I can't see what's been implemented there and what not.

Tell me your opinion: how much native mobile development should I know before learning Dart/Flutter?
Hi everyone, I've been programming for years but have really niched myself into web development (not that there's anything wrong with that-- I just have always had broader/other interests) and was finally thinking I'll try to make some headway into learning mobile development.Tools like Flutter and React Native are so exciting to me, I'd love to see how they progress in the future. It makes me want to dive right in and start learning how to apply everything I currently know about programming to making cross-platform apps.But, I wonder... how much experience should I have in native mobile development before deciding to go cross-platform?As I said, I've mostly been a web developer. I've only coded 2 Android apps during my undergrad, and never an iOS app.I'm truly interested in specifically these cross-platform technologies and where they can lead me (in terms of work and personal development), but should I buckle down and build some native apps and knowledge for both Android and iOS before doing so? I want to know your opinion and reasoning. Thanks for any advice!

Simple CustomPaint vs Containers for drawing chessboard
I completely miss in Flutter's documentation the advantages and disadvantages of doing things differently, especially when to use CustomPaint. I know I can test it myself, but should everyone do? Waste collaborative development time.Imagine that you want to draw a chessboard/checkerboard (8x8 with white or black tiles interchanging).How does the 3 following solutions differ from each other (CPU, memory, render time wise):Create it using rows and columns (or Grid/Table) and each of their children is a Container with color, width and height provided.Same as above but wrap entire board in SizedBox of desired width and height (board dimensions), however individual tiles have only color provided, they are either autosized or each wrapped in Expanded widget if necessary.CustomPaint, paint one big white square of entire board size and than sixteen black tiles placed on top of it.Appreciate your feedback

Google sign in without firebase
I recently found out this video that explains how to google signin in flutter web without firebase pretty easy and straightforward (you can easily do it for app, there's info in the comments on how to). As there is not much documentation about it I think it could be useful for some people if I share it.https://www.youtube.com/watch?v=52DM6y4lFaQ

Best Practice for Authentication using JWT in Flutter?
Hello! I am a fullstack developer who's testing the waters of mobile app development with Flutter. I have an existing backend, which is capable of handling OAuth2 using Google or Facebook IDPs. The flow for the frontend React app is something along the lines of this:
1. Click on login with google
2. Proc a consent screen
3. Google or FB send their tokens and user data to a callback URL on the backend
4. Backend generates JWT
5. Backend redirects the frontend to a URL with the generated JWTs in the URL behind a # sign
6. Frontend parses the URL, extracts the JWT and saves them into the state managerPresuming that I want to use the same Auth flow on the existing Backend, how would this be handled differently in a Flutter app? My main concerns are steps 2, 5 and 6. I am not quite too sure how the consent screen is handled on mobile apps, and how can the backend send back the tokens using the HTTP redirect method (is this even possible?).Thank you!

How do you name your data classes?
I am learning Flutter at the moment and it strikes me that many of the Widgets use very simple names that I have found already collide with names I would normally use to store plain-old-data.What do you experienced Flutter devs do about this? Do you use a suffix like Data or something on data classes?
