New to Dart. What does this line of code mean?
This is the whole line:

Function(String) get changeEmail => _emailController.sink.add; 

I'm trying to learn how BLoC and rxdart works. I'm confused about the left part of this line.

Function(String) get changeEmail => 

I understand that get is a shortcut for creating a getter function. My understanding of Function(String) is that it's a lexical closure and it might be using get changeEmail as part of its lexical scope.I'm confused because I find it strange that a getter is doing something that results in a mutation. My instincts say that it's wrong, but I'm almost sure that I'm wrong. Can anyone break this down for me? Also, is there another way to write this code?

How to navigate to the home page after check the valid token from storage.
Hi everybody, I check the user authorization token at the HomePage Constructor, so if token is present and valid, i will call the Navigator pushAndRemoveUntil method to redirect to my dashboard. But pushAndRemoveUntil method needs context parameter, is that mean i just call it on build method?

Question about app business logic in BLoC pattern
I decided to figure out how to use BLoC pattern for my flutter app. The sources that I used were medium article by Sagar Suri and documentation of BLoC library by Felix Angelov. Both sources suggest the similar architecture:uiScreen <-----> bloc <-----> repository <-----> dataThey say the purpose of the BLoC is to decouple ui and business logic.But I still feel that the whole layer is missing between bloc and repository. Every bloc is mapped to a screen so it is more like controller of ui state and not the business logic of the application because app's business logic is often ui agnostic. So basically if you handle your app's business logic inside bloc you just failed the only task BLoC had. Because now business logic is coupled with particular screen. And what will happen if for example you moved a button that initiated some processing from one screen to another? I guess you would have to move the part of business logic from one bloc to another.So I feel the real need to introduce something like services or interactors layer, where I would do the REAL business logic processing(some calculations, ML stuff, processing data from sensors or system broadcasts or whatever) which I would be able to use in blocs in case I need to show something to user or get input from user.The question is if it ok to do like this? And if yes how would I pass data from services to ui? In native Android ViewModel(some kind of alternative to bloc) could just pass observables from data layer to ui. But in BLoC pattern the stream which is passed to ui is stream of states not of data. And service layer should not know about states of some screen. So do I just await asynchronous services operations inside blocs and then convert this data to streams of states?Any help would be appreciated.

how to get gallery screen on my app
Not like an image picker where you pick images from the gallery but an app that opens up to a gallery screen with all images from gallery. From here i need to select the image i want to do some processing on the server side and get it back.

Spent a couple days with Flutter, here is my experience
I don't see a lot of beginner feedback posts around here, so I'd like to make one.So I've spent my last couple days with Flutter and I thought I would share a couple things I've encountered and the first impression I've gotten.Okay, so here they are:Declarative UI is awesome indeed. Flutter got it right I guess. It is the very same thing that React has with components, but styling is so much better done this way. redux fits nicely with the architecture, would not do the UI any other way.Hot reload is awesome.UI errors are not descriptive enough. You get an error with a failed assertion somewhere and good luck trying to figure out what Widget composition caused the error. Though given the hot reload, you can build up everything iteratively. So like a good 100 times faster compared to native Android development.Android Studio has no working autocomplete. (I cannot emphasize how painful that is.) If you type in the class entirely, you can press Alt + Enter to import it. Though it works with VS Code, which is a joke. Dart alone by itself used in IntelliJ Ultimate on the other hand has the Java-like autocomplete you would expect (it is even enough writing only the uppercase letters). If I open Flutter project in IntelliJ, autocomplete stops working.About Dart:Dart is bad, coming from Kotlin or TypeScript. It has all the downsides with generating toString endlessly for dto classes (and also named parameter constructors have to written by hand, there is no shortcut). The built_value generator is too difficult to set up, it would take yet a couple hours again.mixins, aka 'classy multiple inheritance' makes me fear what it would like to work on the code with other people.factory constructors do not make much sense, implicit interface seems less descriptive and there is yet another new way to type lambda expressions.dynamic and noSuchMethod is just funny, given that it also has reified generics.there are no libraries. Get used to use libraries with 100 stars or less. (With web, I would not even touch anything below 2000 stars.) Everything seems hacky and there is no clear-cut way. Sqlite is also more verbose, given that there is no Room.Overall, there are sooo many weird things in the dart language itself and it's a very unpleasant experience. It looks like what I gain on hot reload I lose on writing repetitive code, which I hope to be able to reduce a lot.

What tool do you use to create your designs/wireframes?
I'm new to mobile development, and jumped in right ahead on Flutter. I'l loving it so far.I've became experienced enough to start designing my mobile apps before starting development. Before I used to jump right into development and design along developing...​What tool do you recommend for designing flutter/material applications, and even maybe work on a wireframe.I'm on Ubuntu, so I would prefer a cross-platform tool.​I've done some researches, and found Sketch to be leading so far?​Thank you
