Is it possible to export swift app to flutter to start cross platform coding?
Hey all, I'm new to flutter and i'm trying to use it to help me cross platform code with an app I've already started working on in swift. I'm not as familiar with flutter and want to see if there were anyway to import what I already have into flutter and continue working?I know its a longshot but, I got to know if this is possible.

Flutter Firebase Auth Signout
Hey everyone! I'm a new developer and hopefully this place is nicer that Slack Overflow.... -_- I followed this tutorial for my flutter app: (The link is the final video of 6) https://www.youtube.com/watch?v=GDrlQ0L4ogg&t=358s I however can't seem to figure out how to get my signout to work.

BLOC and Snackbar
Using the BLOC pattern, I created an output stream of string, on which I send error or success messages to keep the user updated about background operations.The problem is I want to show this messages in a Snackbar, which need a BuildContext to be shown, so I tried to add this at the beginning of my build method :dart myBloc.onLoadResultMessage.listen((message) => Scaffold.of(context).showSnackBar( SnackBar( content: Text(message) ) ), );It kinda work but show me the same message multiple times. I thought it was because of multiple call to the build method but even if I add a bool isListening to make sure it only listen once, I still have the same problem.What am I doing wrong ?

Is there anything wrong with defining your BLoC as a global variable?
Most of the tutorials on BLoC use Inherited Widgets. The way I do it is to make a global variable inside of my BLoC class (final bloc = MyBloc() ) and use this variable wherever I need it.Are there any drawbacks to this approach?

Convince company to use Flutter 1.0?
My company is considering but reluctant to use Flutter because it's "1.0". I made the counter argument that React Native is only version "0.57", not even "1.0" ha... any other ways to persuade my company to try Flutter?

When call setState?
Hi Everyone!​When do we have to call setState method in stateful widget? I know we need call when we change state object which will cause change in UI. But do we need call when there will be no change in UI? Using Flutter example if we are increment counter but not display in UI (just store in in variable) do we need call setState or will variable still be update so we can use incremented value later if pass to new widget.​I have been read Flutter docs to try answer my question but no find.https://docs.flutter.io/flutter/widgets/State/setState.html

I need to display the writing prompt in the top of the screen while the user can write the essay below.I’d like to allow the user to select the key words in the prompt and highlight them to help them stay focused on the topic while writing. How can it be achieved?

Asynchronous Programming in Flutter with Dart (IUE Presentation)
I recently gave a presentation in our university about Flutter and Dart. Please enjoy: https://www.youtube.com/watch?v=yyvTrXCDdYgFrom the video description:Understanding how asynchronous programming works can be a challenge. In this talk tried to give an intuitive introduction to it and compared it to alternatives. I try to answer these questions throughout the presentation:- What can you with Dart?- Why should you use Dart and Flutter?- What is asynchronous programming and how does it relate to callback functions, threads or promises/futures?- How can we write asynchronous code in Dart?- How does asynchrony help in Flutter?This was a presentation that I gave in Izmir University of Economics. It is an improved version of a talk I gave about a month earlier: https://gdgizmir.org/schedule/day1?se...I use ideas from Florian Loitsch's talk in 2015 https://www.youtube.com/watch?v=MUDOI... Hope you find it useful!​

Help a friend out
I made a custom input widget by wrapping Textfield in some widgets and so on. Now I can't reach the onChanged property directly from input. I tried making a property in my custom widget but couldn't implement it properly. I googled passing variables between widgets and it seems a hard thing to do. So any help?
