Snowflake effect
Can anyone help with an effect where snowflakes are falling down the page please. Or better still point me to a library/tutorial that will help me do it myself.

Architecture of the Google Play Brasil Best App of 2019. 1.5M+ installs, score 4.9 with 68.000+ ratings.
Hi everyone! I'm Ricardo from Cíngulo (www.cingulo.com). Our app has been featured by Google Play as the Best App of 2019 for Brazil. We have 1.500.000+ installs and a score of 4.9 on the store with 68.000+ ratings.We have published a very similar architecture as the one we are using at https://github.com/cingulo/flutter-sample . This sample app is fully working, with a sample API also available.It took us about 3 months to build the app from zero knowledge about Flutter. When we started, it was hard to find fully working, complete examples to play with. This is why we have decided to publish this project.Every project may have its own architecture. This is what worked for us. There are still improvements to be done but it already is a good starting point and it would have helped us a lot if had something similar to this when we started.This post is not intended to promote our app as it actually is not even available in most countries and we already have good numbers. But I did mention our numbers to show that this architecture has already reached many people and is working very well. Anyway, if moderators find this an unwanted promotion, remove the post.Hope it can be useful for some, it would have been for us :)

Any solution to using Flutter + Firebase Auth + Apple Sign In?
My app just got denied because I had Google Sign In but now Apple Sign In. I would love a fix very soon.

Calculator App made with Flutter
Hey guys!I recently started learning flutter and just made my first calculator from it. Would love to get any feedback on the code behind it. I'm sure there's a much more efficient way of what I made so I'm open to criticism. The link to the code:https://github.com/createdbymitch/flatcalculatorfollow me on instagram @ createdbymitch I'm doing a 100 day coding challenge!

What are some use cases of auth sign in with Google/Facebook etc without Firebase/server side auth?
This Flutter tutorial video https://www.youtube.com/watch?v=8o-DJDi2bmQ explains how to use Google Sign In without Firebase. Basically the app just uses Google Sign In SDK to retrieve the access token and user info. There is no server side auth such as Firebase involved. One scenario where you implement auth in this way is when your app is a client of the provider's service, for example writing a Google Drive client or Facebook client or Reddit client. Are there some other use cases or types of mobile app that one could just implement auth this way without involving server side auth?

Flutter UI videos and what content you’d like to see on YouTube
Hi guys, I’ve stumbled across a post in this subreddit concerning YouTube creators and the amount of UI videos. Here is the postI’ve wondered what type of content you guys like to see on Youtube?(expect the ones mentioned in the post) What do you guys think about speed code videos? What do you think about those ‘App from scratch’ videos that aren’t really meant to be tutorials?Because I really enjoy watching those types of videos😅Would really appreciate everything you guys have to say on the topic.Thanks guys

Re: New breaking change policy and invitation to contribute tests
In principle anything is fair game, but during the review process we may call certain things out as poor practice and suggest different approaches. Currently only things that can be reliably tested from Cirrus are welcome. That said, there have been experiments in driving there Firebase Test Lab

Why StatelessWidget AND StatefulWidget exists, why not just Widget?
As an experienced mobile developer, I would like to understand why did the Flutter team make this kind of division?Wouldn't it be simpler if all widgets were stateful, without the additional state class - all state methods within the widget class (AFAIR similar to react native)?One less thing to learn, understand, think about, post on Reddit about.If you want you call setState, if you don't than you don't, or you use provider. Is there any performance penalty when using stateful widget over stateless, without using any stateful widget's features?Is there any reason why Checkbox is a stateless widget, and TextField a stateful? And I believe inside the source of checkbox there must be a stateful widget responsible for checkmark animation (on mobile, can't check source at this moment).One can always create a stateless widget and then wrap it in stateful one.Eventually the setState method is called from within widget (it's state), so the other classes shouldn't even careLooking forward to having interesting discussion fellow flutterists.
