Flutter driver support for Native UI elements (webview)
Hi, Does Flutter have any plan to support native UI elements such as Webview and System dialogs? This is an integration test blocker for apps that use native components. I noticed they are working on an espresso library to allow native UI test to access flutter view but that would require us to

setState() or markNeedsBuild() called during build flutter_bloc and provider mix?
Hello, I am using provider and flutter_bluc in my app. Right now I am struggling with this case: A new state is passed to BlocBuilder, which rebuilds part of the Widget Tree UI. What I want is to also update my bottomNavigationVisibility, which extends ChangeNotifier. I use this bottomNavigationVisibility for updating another part of the widget tree. That way I could easily achieve good separation logic for my UIViews IMHO.
However, right now I am always getting this error:
setState() or markNeedsBuild() called during build.Here are the code samples:

 @override Widget build(BuildContext context) { final bottomNavigationVisibility = Provider.of<ProviderBottomNavigation>(context); ... Container( height: 60.0, child: BlocBuilder<SoundsblocBloc, SoundsblocState>( condition: (previousState, state) { if (previousState is InitialSoundsblocLoading) return true; return false; }, builder: (context, state) { if (state is InitialSoundsblocLoaded) { if (state.sounds .where((sound) => sound.focused) .toList() .isEmpty) { bottomNavigationVisibility.isVisibleT(false); } else { bottomNavigationVisibility.isVisibleT(true); } } return ListView.builder( itemCount: listOfSounds.length, ... })), 

​

class ProviderBottomNavigation extends ChangeNotifier { bool _isVisible = false; bool get isVisible => _isVisible; void isVisibleT(bool val) { _isVisible = val; notifyListeners(); } } 

How should I change my code to update my ChangeNotifier from the widget, after a particular bloc state was returned?Also, could I be wrong and using the Provider for separate UI parts with flutter_bloc is a bad combo? Sorry, if I am really wrong, but state management gives me headaches :(

Can we have a weekly or monthly self promotion day?
/r/Apple has a self promotion Saturday and it's working great. I believe this could work here as well. Some people (me included, not gonna lie) want to earn a few bucks with their apps and it's sad that they can't share their work on this subreddit.With the right rules we could have self promotion without turning /r/FlutterDev into an advertising platform. The first and most important being that it would only be allowed on certain days. Here are a few other suggestions:- the author has to list the packages he has used- he has to explain which state management solution he has used- he should share the problems he has faced and how he managed to solve them- he should share some code snippets

Is it a good idea to look for a Flutter Dev on Upwork?
So basically after 6 years of work as an Android dev I have this idea of my own app that I want to build with Flutter and Firebase. The thing is that I work full-time so have very limited time to do this after hours which is why I consider finding a contractor to do this for me. This time I would prefer to take care more of the business side of things not technology. Given that I have a lot of experience in Android and software engineering in general and I also know Flutter and Firebase I should be able to evaluate the quality of his work. Do you think it is a good idea to outsource such work through Upwork or similar platforms or will I just waste my time and money and not get anything of reasonable quality in return, which seems to be a common scenario in such situations?

How customizable is the theming/look of an app built with flutter?
Hi all,New to flutter and mobile development in general. Creating a simple marketplace of sorts and just wondering if I am giving up any branding/looks by using flutter. It seems like many of the built in cross platform components use material design and I’m just curious if that will limit my styling abilities compared to native iOS.Thanks!

Flutter Internals: a (free) book that explains how Flutter works.
I'm excited to (FINALLY!) release a free, open source "book" on how Flutter does what it does:https://www.flutterinternals.org/I posted about this project a few weeks back and was blown away by all your amazing feedback and support.It's taken a bit to find a way to continue expanding and revising the text in a collaborative, community-driven way -- but with your advice (and GitBook's generosity), I'm proud to share Flutter Internals with everyone today.The book is a bit more like SparkNotes than an actually programming text, but hopefully the material and explanations are still insightful. My hope is that the content is comprehensive and easily understood without being too wordy (or taking too long to read).Last but not least: please check out the "Get Involved" page -- I think this is a resource that will only become more valuable and useful with the community's support.Looking forward to your feedback (and please consider joining as a contributor!)
