What do you think Flutter Web Stable should have?
I tried FLutter web and here is my summary of why Flutter web is not ready:1- I use SVG only in my app for responsive and small size icons but Flutter SVG library is not supporting the flutter web yet because of dart paint is not fully support web.2- Several libraries depend on dart:io package like Connectivity and Firestore but dart:io is not supported on Web https://github.com/flutter/flutter/issues/399983- Errors on non-supported plugins are not clear on which plugin does not support the web and you can see the crash only in the runtime.4- Breakpoints don't show the variable value while debugging only you can print it.5- When you resize the app on Chrome you feel the render is lagging and it could show error while resizing the window.6- While evaluating your app for Flutter web you will face the CORS policy issue which requires some changes in the backend.
I asked for ignoring chrome CORS security for playing with Flutter web but my proposal is rejected
https://github.com/flutter/flutter/issues/46904
https://github.com/dart-lang/webdev/issues/862I have to ask Python AWS developer and PHP developer to allow CORS for my request and I have to add a fixed port in my launch.json"configurations": [
{
"name": "Flutter",
"request": "launch",
"type": "dart",
"args": [
"--web-port",
"8080"
]
}
]7- Google maps plugin is not ready for Web

Tighten up you type checking in preparation of NNBD
If you already use

implicit-casts: false implicit-dynamic: false 

you will learn nothing new from reading this.Did you ever write something like

List<int> filterEven(List<int> ints){ return ints.where((item) => item % 2 == 0)); } 

which compiles fine, only to get a runtime error, and were annoyed that the Iterable got implicitly downcasted to List by the dart compiler, even though that will fail at runtime?There is a setting that turns this implicit downcasts off. Just add

analyzer: exclude: [build/**, lib/**/*.g.dart] strong-mode: implicit-casts: false 

To your analysis_options.yaml. This will be the default setting once NNBD is released (Source), so I really recommend turning this on.You might have to do some minor changes to your project, but nothing too bad.While you're at it, you also might want to add

implicit-dynamic: false 

to your analysis_options.yaml.This stops the type-inferrer from inferring dynamic, except when you specify the type dynamic explicitly. I strongly recommend turning this on, too. An implicitly inferred dynamic can cause really strange behavior, for example in this case:https://dartpad.dev/b42203ba5d7d8e5ff55f99bd003a81bfThe programmer forgot to add the generic type to the "extends" definition, and now gets the cryptic error message

Expected a value of type '(dynamic) => Widget', but got one of type '(int) => Text' 

To turn this in a compiler error at the right place, use

 implicit-dynamic: false 

One annoying downside of this is that you have to add the dynamic type explicitly, even when a method expects a dynamic type, e.g. if there is a method

Foo deserialize(Map<String, dynamic> jsonMap) 

you need to call it like this:

deserialize(<Map<String,dynamic>> {"key": "value"}); 

But I would still argue this feature is worth some additional boilerplate.

Is it possible to develop with flutter without an IDE?
I'm a bit old school in that I develop in generic text editors (vim and gedit on ubuntu, primarily). I'm interested in developing with flutter and built a container with the android sdk and flutter, but most tutorials seem to rely on using an IDE. Is there any tutorial out there that shows development on the command line, or similar? Thank you!

Little help here putting logic on icons
I have this list

final List<String> entries = <String>['Life', 'Car', 'Car']; 

then i try to generate 3 widgets each one with an icon depending on the values that have the array i tried in this way

 children:<Widget>[ Icon( entries=='Life'? Icons.favorite_border:Icons.directions_car, color: Colors.white, textDirection: TextDirection.ltr, size:50, ), 

but all widgets get the favorite_border icon instead of mixing between directions_car and favorite_border.
