How to remove markers from a flutter leaflet map? I used this program .But, it is not working. When I uncomment the traveler_markers = traveler_markers2; (after print statement)it removes all markers from other functions also. I want to remove only this set of marker from the super set.

How do you use BLoC - Flutter Bloc
So recently I've been thinking about a way to structure my blocs in a way that would be simple and intuitive. So I came up with two ways:One event - One data - One stateSo this one is quite simple to understand: When a public event is triggered, only one type of data will be fetched/loaded and this data and only this data will be yield, which means that if you need to fetch/load more data you'll need what I call a private event. Those private events are triggered by previous events.I've come to find that this method works best with freezed and yield by copyWith.Here's a visual representation of how it works:Public event Data loaded Yield state.copyWith Private event Data loaded Yield state.copyWith etc...Here a code example:```dart yield* event.map( publicEvent: (event) async* { User user = await loadUser();

 yield state.copyWith( user: user, ); add(const MyBloc.privateEvent1()); }, privateEvent1: (event) async* { List<Post> posts = await loadPosts(); yield state.copyWith( posts: posts, ); if (something) { add(const MyBloc.privateEvent2()); } }, privateEvent2: (event) async* { List<Draft> drafts = await loadDrafts(); yield state.copyWith( drafts: drafts, ); }, 

); ```This method seems to ensure that the code in each event is short and readable. It also more or less respect the single responsibility principle by allowing one API call per event.A drawback I find with this method is that the more private events and condition you have the more complex it becomes to keep in mind how the entire logic flow. I have to admit that I had to use drawio to have a visual representation of the logic flow.I haven't been able to found any significant performance issues even with 10+ consecutive private events.One event - One stateThis one is the simplest way to structure your bloc. An event is triggered, you fetch/load all the data you need for this event and then you yield them all.Here's a visual representation of how it works:Event Data loaded Data loaded Data loaded Yield stateHere a code example:```dart yield* event.map( publicEvent: (event) async* { User user = await loadUser(); List<Post> posts - await loadPosts();

 List<Draft> drafts = <Draft>[]; if (something) { drafts = await loadDrafts(); } yield state.copyWith( user: user, posts: posts, drafts: drafts, ); }, 

); ```This method has the merit of being direct. You have everything you need in one place and it's easy to have a visual representation of the logic flow.The problem I personally have with this method is having this much calls in one place. The more data you need to fetch/load and the more condition you have, the more bloated the code becomes.Overall I don't have a preference for either of these methods and I use them as I see fit but I would like to have a method that I can use all over my codebase for consistency reason.If you have your own way of structuring blocs please feel free to share, hopefully, we'll be able to find a "universal" structure.

Flutter Web Scrolling
The performance of the scrolling and the feel in Flutter Web is really not on the level that I would like. It's laggy and there is no scrollbar.I have made packages for each problem, so feel free to use them. I created both of them almost from scratch. You can find them in the following links:Smooth ScrollingScrollbar For Flutter WebI hope it can help you guys. We should use Flutter on the web regardless it is only available on the beta channel, but I have been developing with Flutter web, and the experience is a lot better than a year ago.

Flutter app to track smartphone app activity?
Hello all,I want to create a system to track my smartphone use and see which apps I use most often and in what time frames. I am trying to cut down on smartphone use and seeing the trends and number would help me. Are there any packages/apps you know of using Flutter that can track app activity?Note, this will most likely be for personal use only so asking for permissions is not an issue here. If I create the app, I want to be able to control my own data, thus I would prefer to build the app myself.Thanks in advance!

Flutter Web, the chance to make websites
Does anyone here don't like html, css etc, and because of this don't develop websites? just apps, and with Flutter Web got excited to build some websites?I personally don't like html css, I was always avoiding to learn web development, now I might start studying React, since flutter web might take a long time to really be ready for production.Plus, People say that web apps is not the same etc...Anyone in the same situation?

CompleterEx - a package for diagnosing Completers that don't complete.
CompleteEx is a simple package that wraps a dart Completer.https://pub.dev/packages/completer_exIt works exactly as a Completer does and is a drop in replacement.So why use CompleterEx?If you fail to 'complete' a Completer it can be close to impossible to find the problem completer.CompleterEx solves this problem by logging any completer that hasn't completed within a given time period (10 seconds by default).It then logs the stacktrace to the code that created the completer making it easy to find the problem code.I've spent hours trying to track down completer problems. This class makes the problem obvious.
