question about cost of widgets
so i can't find anywhere in the docs (or anywhere) anything about the cost of widgets when it comes to: memory, cpu usage, storage, etc. i think that this would be super useful for my and everybody's projects, so I can help optimize my app. so if anybody can find this information anywhere, i would really appreciate it. and if anybody would want to work on a program that could display this, i'm totally down. DM me.

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.

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

How to highlight a displayed text in flutter?
I’m building a mock writing test app with flutter. 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?
