Flutter android imagepicker permissions
In the recent post for data protection page Android/playstore made it clear if you're taking images/videos from a device you need to ask permission.Declares at least one of the following permissions: READ_EXTERNAL_STORAGE WRITE_EXTERNAL_STORAGENow flutter imagepicker isNo configuration required - the plugin should work out of the box.And if I am asking permission explicitly app is not responding to the permission means not invoking what should I do. Flutter image-picker explicitly ask permission I am only picking images. Then uploading it to firebase.

Best way to ramp up senior dev to Flutter?
I’m currently researching some options for the company I work for to start building some basic mobile apps. We’re a small team, so I’m trying to avoid the traditional approach of building out Android and iOS apps separately. I tried React Native a few years ago, and wasn’t impressed with it.I have 11 years of professional experience as a software engineer, but it’s been mostly C# MVC patterned web applications, short stent with C#, Xamarin Ruby on Rails, SQL Server (maintained some nasty stored procedures), few years of Swift (mostly api and service layers, someone else did the storyboard designs/UI), restful and graphql API creation/maintenance/consumption.With all that said, what’s the best way for me to jump into Flutter/Dart? I don’t mind “Drinking from the fire hose”, but I want the good quality water. I’m looking for some great videos, tutorials, weekly series (I love gorails), VS Code tips, flutter design patterns, garbage collection advice, “must have” flutter tools/components/plugins, or anything else that you wish you had known when you first started with Flutter!I don’t want to have to sit in front of our CIO in a year explaining why we have to rewrite our app(s) in Swift and Java because we decided to go with Flutter.Thanks in advance!

What was your favorite flutter project you've made/contributed to and why?
Please leave a repository link if you can; Mine is Corona Spectator, and it's my favorite because it was one of the first times I actually felt like I was solving a real world problem with my programming skills.

Flutter Devs: Problems & Pain Points
Hey All!Hope everyone is doing well. I created a short survey to understand what the largest pain points for flutter devs are. It should only take a minute or two to complete. I would really appreciate if some of you would fill it out.https://forms.gle/qyEefi7n67eLzzsF8Thanks!

State Management Example Using Riverpod
An example how I use immutable models with Riverpod.I have an immutable Game. I also have a bunch of update functions to transform one Game state into the next state, for example to move something forward, there is a moveForward function that returns an Update<Game> function that does whatever is required by the rules:
typedef Update<T> = T Function(T); Update<Game> moveForward() => (game) { final nposition = game.position.step(); if (!game.map.isValid(nposition)) return game; return game.update(position: nposition); }; Now I want to combine this approach with Riverpod.I have to create a subclass of StateNotifier to store my Game (or any other updateable value because I'm doing this is the most generic way of course):class UpdateableStateNotifier<T> extends StateNotifier<T> { UpdateableStateNotifier(T initialState) : super(initialState); void apply(Update<T> update) => state = update(state); ... To make creating a provider look nicer and to omit all the explicit types otherwise required, I also provide this utility factory function:... static StateNotifierProvider<UpdateableStateNotifier<T>, T> provider<T>(T initialState) => StateNotifierProvider((_) => UpdateableStateNotifier(initialState)); }Then I can setup my gameProvider like so:
final gameProvider = UpdateableStateNotifier.provider(initialGame);Later, I can access the current game state as usual:
Widget build(BuildContext context, WidgetRef ref) { final game = ref.watch(gameProvider); ... To easily apply updates, I extended WidgetRef:extension UpdateableStateNotifierExtension on WidgetRef { void apply<S>(StateNotifierProvider<UpdateableStateNotifier<S>, S> provider, Update<S> update) { read(provider.notifier).apply(update); } } Now, my UI can do this in callbacks or other actions:ref.apply(gameProvider, moveForward());There is a bit more work involved because I also support undo (and redo, because why not) and Update actually returns a FutureOr<T>, but the principle stays the same.

BLoC vs Riverpod
It seems commercial programming requires BLoC. Maybe this is more a legacy of older Flutter. For those who've used both, do you think BLoC has enough to offer over Riverpod to be as necessary as the commercial market has made it, or should it fade away for being so complex?Obviously there are those who will say "use both" or "it depends" but what I'm trying to get to the bottom of is: really how valuable is BLoC that new developers have to get their minds around it in addition to the complexities already in Flutter.View Poll

What are common ways to do application structure and architecture in Flutter?
I would like to decide on an application structure and architecture for the app I'm building that will be scalable and easily readable for other people in the future.There is supprisingly little information online on how to approach those things in Flutter. What are some common ways to do that? Should I go for architectures like MVC or MVVM or are there other viable options for Flutter? And are there some good tutorials by example available for that?

Have you switched from stream-based state management to any other and why?
I've been developing Flutter apps since the early 2018, and what got me in love with streams was a 2018 I/O talk by Matt and Filip from the Flutter team, which looks like it has since been deleted.I've lucked out at my current job and got to decide on the state management approach, obviously I've went for something I'm well familiar with, and that's using StreamBuilder, StreamSubscription and Stream objects to handle state management (alongside some setState and StatefulBuilder widgets here and there). We've built a functionally very large webshop, and are on the track to release it! I'm actually surprised by how little bugs we've encountered, so I don't think complexity is an issue.My question is: have you used stream-based solutions in a professional capacity, and have you switched from it to any other solution and why? If it means anything, my colleagues seem to have gotten a good grip on streams, so that's not a concern.Many thanks.EDIT: Any issues you've noticed that resulted in you not choosing stream-based state management?

ListView Render Behaviour
I am creating a chat page as part of a project I'm working on. In a demo, I run a bit of logic in the ListView.builder to obtain the details of the next chat message to inform specific UI rendering. To be precise, the structure of the message widget should change if it was the last of its "kind" like WhatsApp does.To test this, I passed two arguments to the message widget; <message> the actual message, and <next>, the one after. If the message was the last in the list, then <next> would be null.I gave it a test run with some dummy data. The messages would not render a date unless they were the last from either myself or someone else. All was well.At least, until I tried to update the dummy message list with new data. The previous "last" message widgets seem to maintain the "null" value of <next> even though they are no longer the last. It's quite an interesting situation because values like the index and message list length were refreshing predictably when I chose to display them. InitState was also being called for each widget.Does anyone have an idea of what is happening behind the scenes?PS: I plan to achieve this differently, in practice. The chat pages are ephemeral, so I assume I can get away with some stuff, but any advice is still welcome.

How do you comprehend abstraction
Hey all, I have been learning Bloc and I thought I was at a decent level enough to dive deeper into the tutorials but I don't understand why some things are done at this point. I know that Bloc is famous for its boilerplate but that's not at all the issue here. It's everything else.I know you are supposed to abstract certain details in your app so that they are reusable or can be changed without affecting other components too much but it gets to a point where I'm lost and I don't understand what does what and why we are separating it into its own module.It was a simple weather app that I got lost with and I don't know how anyone can understand production level code. I've only built apps for myself and only recently started collaborating on GitHub so that might be it but the confusion I get from reading some code and not immediately understanding what it does makes me want to give up sometimes.I do understand the code I see in front of me but conceptualizing how everything comes together seems too much for my head. It's strange to look like a chore especially when it comes to testing large swaths of code.
