As FaunaDB documentation, it seems that there is no dart API nor REST API. Also, I can't find the FaunaDB package in the Flutter Packages.
Is there any way to use the FaunaDB on the flutter?
I think the easiest way to use Flutter with FaunaDB is to use FaunaDB's GraphQL interface and Dart package graphql_flutter.
I recently managed to read data from FaunaDB using graphql_flutter, and will update this post when I have tested it more.
Currently we don't offer first party support for flutter. You can build a third-party driver for Dart based on our current open source drivers if you'd like. They do use json/http under the hood. If you are targeting android another option might be to fork the java driver and switch out http clients to be android friendly and use a platform channel.
Dart is able to use javascript libraries

You can simply use the javascript driver

Recently there was a new package published that can help you to use faunaDB with dart/flutter: faunadb_http This library also provides query classes that closely mimic FQL functions.

I am desperately trying to figure out how to initializeApp with Flutter (not React Native).
I know about the functions to use, but I can not find the firebaseConfig I need to pass into the function.
And no matter what I search for, every resources references to React Native, like as if nobody codes with Flutter since Firebase 9 has been released anymore (or I am the only dummy which is not able to resolve this by myself).
Can someone tell me where to get the firebaseConfig object from?
If I add a new app to my project, I only get the google-services.json, which does NOT include the firebaseConfig object I need to pass.
I understand your confusion now, let me explain. When the guy in the video talks about Firebase v9 he is talking about the SDK version which in the case of Javascript (which I suppose is his main topic in his channel) is currently 9.17.1 an the version 9 has been around since 2021 so it is not new. The different SDKs have their own versions for each platform so thinking it will be the same in every SDK is a mistake by itself. You can check the SDKS here. So there is no Firebase v9, there is a Firebase SDK for javascript version 9. They managed in that way in javascript and in flutter it is not the same. Being that the last update in the flutter SDK was literally yesterday I'm pretty sure they have their reasons to not implement the same functions in flutter since 2021.
Now, one of the thinks the guy talks in the video is deconstructing, which is something common in javascript. The way you do this in flutter is by using show.
So you would be doing this for example:
import 'package:cloud_firestore/cloud_firestore.dart' show FirebaseFirestore, QuerySnapshot; //Add everything you would be using
This way only the specific parts of the library will be imported and the amount of code the Dart VM has to load will be reduced.
As of the access to documents, it is still the same but you can easily create a helper class that contents your references to your collections and then just use that class to reduce the boilerplate code created by the firebase SDK.
You have to install the Firebase CLI and run firebase init.
You need to use the package firebase_core that will give you access to the class Firebase so you can use it to initialize your app Firebase.initializeApp() you can pass the default options for the current platform using Firebase.initilizeApp(options: DefaultFirebaseOptions.currentPlatform) usually your IDE will automatically import the corresponding package but in case it does not you would have to import 'firebase/firebase_options.dart';

Supabase provides supabase-dart for non-flutter applications and provides supabase-flutter for flutter applications. (The pubspec in supabase-flutter apears to use the supabase-dart package.)
I have dart code files that comprise a data access layer (for the postgres db) written for supabase. I'd like to share the dart code files between a non-flutter, server written in dart and a mobile app that of course is in flutter.
The imports in each code file of the flutter app all use:
import 'package:supabase_flutter/supabase_flutter.dart';
So, I didn't necessarily want to bring those code files into the non-flutter, dart server because they use supabase_flutter.
I have the exact same code files in the non-flutter, dart server but I replaced the imports with:
import 'package:supabase/supabase.dart';
And, it works fine, but I have to maintain two versions of essentially the same file.
For these shared files, is it ok to just use the non-flutter import in both the flutter and non-flutter apps?
(I have tried some combinations of this and things seem to work, but I don't know if there is something I need to be concerned about on this since the docs say to use one package for flutter and the other for non-flutter.)
For these shared files, is it ok to just use the non-flutter import in both the flutter and non-flutter apps?
Short answer yes.
supabase_flutter package is just supabase package wrapped with some Flutter specific code mainly to bring auth persistence, so you should be fine importing supabase package for some common pieces!
I want to make a Flutter app that can play YouTube playlists using the YouTube Android Player API, found here: https://developers.google.com/youtube/android/player
The "Getting started" instructions say:
The following documents will help you to set up your development environment and use the YouTube Android Player API:
The download page provides a link to download the API client library
and JavaDocs.
The instructions for registering your application explain how to
register your app in the Google API Console and to obtain an Android
API key, which you will need to use the API.
The setup instructions explain how to set up an API project using
either Eclipse or IntelliJ.
The sample applications overview describes the sample applications
included in the API download.
The JavaDoc reference provides detailed definitions of the API's
interfaces, classes, methods, and enums.
I've followed every step in those points and links, but I still don't know how to use the provided package in my code! I now have a sample app running on my phone, and apparently using the package... which is cute... but it is in Java, which I don't speak, so it doesn't help me make my own app! Plain English instructions would have been more helpful...
I have tried:
import 'com.google.android.youtube.player'
and even:
import '<path>/YouTubeAndroidPlayerApi.jar'
but Dart Analysis tells me the URL doesn't exists. And when I try any of the classes that are supposed to be included in the package, I get that it's not defined.
I've tried right-clicking on the YouTubeAndroidPlayerApi.jar file and choosing "Add as library", but same result.
So what I normally do is to write something in my pubspec.yaml file, like:
dependencies:
provider: ^4.3.2+3
Then I would run pub get.
Then I would write import <package name> in my code, and now the classes will be ready to use.
What is the correspondence in this case? What am I supposed to do with this package so that I can use the classes in my code? I'm using Android Studio.
Most grateful for guidance!
I know that the availability of dart.library.html can be used as the condition for web, but what about desktop?
Although I suppose you can import a particular package for desktop and not for mobile if you create and use a new package in which different packages are specified for different platforms in pubspec.yaml as explained in the document,
it seems a little redundant to make such a package for that purpose.
Is it possible just by using a statement of the import 'foo.dart' if (...) 'bar.dart' style, and if possible, what library is put in its if (...) part?
You cannot use conditional imports to get different behavior between mobile and desktop; see this comment from the Dart team.
I am creating a Flutter project targeting of Android/iOS and Web is there any way to add the supported packages separately for both the Flutter Mobile and Web. For example, I am using the dart:io package in Flutter mobile applications to save the files, but it is not supported in Flutter web, so for web, I am using the dart:js package to download the files in the web application.
For C# we are simply using conditional symbols but Flutter I could not found any solution.
The problem is I could not import both the packages in my main.dart file. Can anyone help me to achieve this
Dart has conditional imports that can be conditioned on the availability of platform libraries.
That means that you can create one library in your package which uses dart:io, and another which uses dart:js, and then import whichever of these is supported.
import "file_loader.dart" // Version which just throws UnsupportedError
if (dart.library.io) "file_loader_io.dart"
if (dart.library.js) "file_loader_js.dart";
// Use imported API.
The important part is that you give these libraries the same API - the same types
with the same members, and the same top-level function - so that no matter which library is imported, the code that uses it is still valid.
When you compile the program, only one of the libraries will be used, so you won't get warnings if the other libraries are incorrect. You should test the code on all the supported platforms, just to be sure.
You should implement code separately, for example, my_ui_web.dart and my_ui_mobile.dart
Then you can import those files using if:
import 'package:my_awesome_app/my_ui_mobile.dart'
if (dart.library.html) 'package:my_awesome_app/my_ui_web.dart'
as myUI;
