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 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 created an app for a small group of people. I created a lot of widgets/pages and models. Now another group asked if I could make them the app too. I could create a new project and copy/paste al stuff in there, but more groups want this app, and its a lot of work.
My idea was to create something like a package or export the whole code base to another destination, so that I only need to edit one code base and it changes on all app instances. For the new group I only need to change the API URL and some images which can be changed in pub spec.yaml and main.dart. Do you have a working solution for this?
Please read those articles about creating new package:

Also, Pay attention to what is the supported platforms in you package and test it with each platform. You can also publish it to Pub.Dev if you want. but must be on GitHub first.
I'm trying to learn to write Hardware Abstraction Layer (HAL).
Here's the path I've taken so far, please correct me if I'm off in any step.
Downloaded AOSP and built it successfully (86%)
Located Vehicle Hal Support Library
Located android.hardware.automotive.vehicle C++ code.
Things I've attempted after that the steps below without succeeding to get those above classes recognized.
Import android.hardware.automotive.vehicle classes in Android Studio for a typical Android App that targets 29 Api Level.
Adding meta tag of android.car app
Copy/Pasting all source code under AOSP /packages/services/Car/
Partially contemplated adding android.hardware.automotive.vehicle#2.0.so Library and trying to access it through JNI (Not so sure about this one).
Please orient me, I see some repositories on github not doing anything special and somehow they're able to import the package in a java class like this.
import android.hardware.automotive.vehicle.V2_0.VehicleHwKeyInputAction;
import android.hardware.automotive.vehicle.V2_0.VehiclePropValue;
import android.hardware.automotive.vehicle.V2_0.VehicleProperty;
import android.hardware.automotive.vehicle.V2_0.VehiclePropertyAccess;
Here
how on earth do they get access to those classes?
Thanks
Vehicle HAL is not meant to be accessed directly from apps. Car Service does that for you.
You have couple options depending on what you're actually trying to accomplish:
Learn to write HAL services - it's like writing a driver for a given hardware (in this case, something that provides car data to Car Service).
Learn to write HAL clients - try modifying EmbeddedKitchenSink app first. Please note you need to build it with AOSP and not in AmdroidStudio since this is a system app (and regular apps doesn't have access to the HAL)
Learn Vehicle APIs - that's what you need car lib for. Details on how to use it: https://stackoverflow.com/a/63321234/14759774
I want to use the Ionic UI framework with Trigger.io for my hybrid mobile app, but it isn't clear to me just how to combine the two in my code because it's not like using Jquery where you just add the library to a script tag.
After install, both of these frameworks provide their own "hello world" type of index.html file, their own css and js files as well as framework specific configuration files which I know are important. So which one do I use as a base and how do I call into the other framework from that base? How do I structure the project file tree to combine the two so that when I go to do an app build for distribution, there isn't some crazy error because the frameworks are set up to look for their own files via set paths?
Here is one answer I found in my googling.
What steps do I need to take to use the Ionic Framework with trigger.io?
here is an example project on git hub:
https://github.com/travisrussi/ionic-triggerio
here is the link to the ionic cdn to be used for testing:
