Can I replace existing Android folder with files from a new project?
Hi all, so I added a QR reader plugin which worked fine in iOS, but for Android, oh boy. The plugin is written in Kotlin and here we go, trying to make everything work has been a nightmare. Instructions were simple, but man oh man, problem after problem arose.​I have gotten to the point where I'd rather just delete the android folder completely and add a new one. But, how will that affect my project? I realise that I'll have to make changes to the Gradle files for them to be as they were before this mess, but other than that I have only added app icons and so on that I can just put back.​Any tips?

Flutter audio libs
Hi everybody,I'm playing with Dart and Flutter and it seems awesome.I'd like now to try to create some audio player, but it seems that there are not so many available features / libs yet.I've just found 4 plugins, cool to have indeed, but they don't provide me with all the features I'd like.How would you proceed in this case? is it easy to integrate C++ or other language libraries?

Is Flutter right for my project? Looking for input from experienced devs.
Without going too much into boring background details, I'm rolling the dice on a project I've been daydreaming about for a while. The service will be similar to AllTrails. Basically a catalog of places with some highly relational graph data structures but with the ability for users to donate money to the maintainers of those places. The structure currently looks something like this:A graph database powers the backend storage. I currently have a DGraph database running with the foundations of my schema worked out. A server written in Go exposes data to clients through an HTTP API and handles user state. I will also require an events server to fire off emails, push notifications, etc.A client written in Quasar (a Vue.js-based framework similar to Vuetify with more features) for PWA functionality.My first plan was to go web-first then learn Quasar's mobile app building toolchain (Cordova) to publish "native" apps. A PWA would accomplish 99% of what I want so I was going to go with that but Safari still lags horribly and iPhone support will be critical. I also know, at least on Android, the browser API for GPS location is drastically less precise than the native API. That's also important to me. Native apps would be better but if I go that route I need cross-platform capability and I will actually need a web app as well for certain functionality that's just not practical on a mobile screen.Then I discovered flutter-web is a thing in development and I've been digging into that for a few days. If I could make a cross-platform Android and iOS app that could also be served as a web app for desktop keyboard/mouse functionality that would be the best of all worlds.While in that rabbit hole I discovered that Firebase, through a bit of work, can serve up GraphQL and also has a complete auth/user management system. So now I'm also considering scrapping my current backend and refactoring it to work through Firebase which has tight integration with Flutter.I'm interested in any input related to framework choice and Firebase but I have a few specific questions.Can Flutter apps display photospheres? There's strangely zero information coming up on this via Google.The Play Services Location API is supposed to be the most accurate way to get location information on Android. Do any of Flutter's location libraries use this for precise location information? Can they report the accuracy of results similar to how Google Maps displays a variable circle to represent the accuracy of location data?What is your opinion on flutter-web for exposing functionality which is not practical outside of a large screen with a keyboard and mouse?Realistically how critical will having a Mac and/or iPhone be? I have a busted iPhone sitting in a drawer somewhere I could probably repair but I'd rather not buy a Mac just for publishing an iPhone app.Thanks.

Why Flutter is the next-gen mobile app development framework?
Google has always been a game changer when it comes to digital evolution. In the world of software and mobile app development, Google has introduced an open source framework, which is Flutter. It came into public use in Mobile World Congress, 2018. It is Google's creative framework for cross-platform app development.Though it is a new release, it has started gaining popularity, as many companies across the world are using its single codebase SDK for porting their current cross-platform apps.Behind the popularity there are reasons, and know more Why Flutter is the next-gen mobile app development framework? click here

What is the right way of building infinite list view with FutureBuilder and Provider?

FutureBuilder( future: getPosts(), builder: (BuildContext context, AsyncSnapshot snapshot) { return makeListView(context, snapshot.data); } Widget makeListView(Data data) { final notifier = Provider.of<MyNotifier>(context); notifier.setPosts(data); return buildListView(); } void loadMore(BuildContext context) { final notifier = Provider.of<MyNotifier>(context); //handles pagination, fetches new posts then notifies but wouldn't this cause infinite loop? commentsNotifier.fetchOtherPosts(); } 

I'm trying to build an infinite listview using FutureBuilder and Provider. This is what I'm thinking right now but I could also setPosts() like, future:getPosts().then(setPosts()) Also when loadMore method sets the new posts wouldn't it cause infinite loop? What is the right way of doing this?

How can I check in my Firebase whether a user interacted with something?
Hi,​im building a flutter application right now similar to reddit and have to ensure that a user can only upvote once. How can I implement this in my application using Firebase?​In my Firebase I have a collection called "posts", where all the posts are stored. Within that I was thinking on adding a list of users, who already have upvoted the post.​Is that the right approach and technically possible? (I don't think so).​Thanks for any replies,Ducky
