Rumors about Maps in Flutter Apps
Hi! I am a mobile developer.I have heard rumors that Flutter doesn't have fluid maps because of the fact that it manipulates pixels on the screen.
Is it true that the map experience is still not great?The last time I used an app built by Flutter, it was really smooth, and felt like the future.
Thanks

CS basics: Why can phones easily run graphically intensive games, but then have problems with scrolling a ListView at 60fps?
Good day.Over the last few days I read a few articles/blog posts about how Flutter draws widgets to the screen and how there were/(still are?) performance issues when for example scrolling a list. I am only a hobbyist, so I'm lacking a CS background. I really do not understand this:Phones can easily run graphically intensive games with tens/hundreds of thousand polygons, textures, shaders, real-time shadows, particle effects, etc, but then that same phone has problems drawing a simple ListView containing only text and maybe a little icon at 60fps? I must have a massive misunderstanding about how GPUs work or how graphically intense a few simple text fields are.In my mind/logic I would assume that displaying something like the Facebook/Spotify/Whatsapp app would require magnitudes lower GPU load than running a 3D game. However clearly that's not the case. So what am I not understanding here? Does a simple scroll-view really max out my phones GPU (as much as a 3D game would)? Sounds almost unbelievable.Thanks so much in advance

Proposal for extending the Navigator and adding a Router widget
Hello, I've written up a proposal for extending the Navigator with a declarative API that gives you control over the history stack and for adding a Router widget to configure the Navigator based on system events and app state. If you're interested in that, give it a read and leave your

I used Firebase with Flutter for starting and its amazing...but.....
Why arent all apps using whatever method Firebase has for real-time data? The whole pull to refresh idea now seems super super super ghetto......

Unity vs Flutter
I realise this question will be outrageous for some people at first but allow me to explain: Yes, I am aware Unity is a game engine. However, in the past, I used Unity numerous times for developing non-game applications with great results. Therefore, for the sake of the argument, let's forget that Unity is a game engine for a while and let's consider it another multi-platform development framework.What reasons can you think of for choosing Flutter rather than Unity? I have been trying to answer this question for some days now. So I wanted to ask your opinion- especially those who are familiar with both frameworks.PS: One common worry about using Unity for non-game applications seems to be the battery life. The consumption of resources by the Unity Engine can be significantly minimised by optimising the render pipeline. So actually, this is not a problem.

How do you organise your project structure?
I'm really curious, how do you avoid making a snow-ball as your project grows? I started my project (soon to be open source) as widgets/models/util/blocs/screens but as soon as it started to grow, it got less and less maintainable. I'm looking to refactor it, but I don't know what an "optimal" structure would be. Maybe split the directories by screen? But then you have the problem of one screen which is inside another, something that depends on another. Most projects I see out there are simple, with less than five screens, so there is not a lot to observe.I am coming from Android Development and over the years we've got a lot of discussion on how to improve the structure (specially since the XML view system don't allow directores, sometimes you get 100 files in res/layout). So I would like to hear you, how can I and we improve? Here is my current situation: https://imgur.com/Vc3YvWy

Resources for learning flutter design patterns and good practices
TL;DR at bottom.It's been 4 months since i started learning Flutter with no background of mobile app development but at that time i had a good understanding of basic web apps and object oriented programming as a computer engineering freshman.Right now i can make basic CRUD apps with user auth in Flutter with Firebase or my custom made server in node. The biggest problem i have is the design patterns for flutter projects. For state management i have used scoped model, provider. I also learned about BLoC pattern but it felt overkill for my projects.The problem i have is general design patterns of flutter development or any kind of mobile app development.I don't know how to structure my project folders/files/code. I know how to seperate my ui from logic but i don't know the best practices and i couldn't find good resources about patterns.TL;DR: Where can i learn how to develop good structured scalable apps and best practices for Flutter? I am not looking for a resource that teaches me flutter. I am looking for a resource that teaches me design patterns and best practices.

Flutter Installation
hi, I am trying to install flutter on linux, ubuntu.I have the sdk up to date.I followed the UPDATED tutorial from academind on youtube "Flutter Crash Curse For Beginners 2019" (skip to the mac installation part, there is a time map in the descripition)and when he says to run "flutter doctor", I always get an error that looks like this:"flutter: command not found"This is how my ".bash_profile" looks like:

export PATH="$PATH:/home/andry/Desktop/Flutter Folder/flutter/bin" 

Is my .bash_profile incomplete or something?If you can help, that would be massively appreciated.

Deserializing complex JSON objects using built_value
​ I am trying to use built_value to deserialize a complex JSON object that changes it type based on a specific key, as shown below. (This is basically an output from Prosemirror WYSIWYG editor)

{ "type": "paragraph", "content": [ { "text": " It was, the Honolulu Star-Advertiser explained", "type": "text" }, { "type": "hard_break" }, { "text": "Her rise coincided with a surge in donations.. ", "type": "text" }, { "type": "hard_break" }, { "text": "News reports from the region, however, contradict this claim.", "type": "text", "marks": [ { "type": "em" } ] } ] } 

Here you can see that in the content array, objects are to be deserialized as separate classes. (Ie: There should be a Paragraph class and under that there should be a Text class and a HardBreak class)I went through the built_value docs and could not figure out how to proceed. Can anyone help me with a possible strategy to deal with such non uniform JSON payload scenarios?
