What is hub_android?

hub_android is the Android build configuration folder for a mobile app called CixioHub, which is part of a course project. The app itself is built with Flutter, a framework that lets developers write a single Dart codebase and compile it to both Android and iOS at the same time. This particular repository contains the Android-specific build settings that Flutter generates automatically. The README notes that developers rarely need to edit the files here directly, and that the actual application code lives in a separate mobile/ directory. The README is written as instructions for an Android developer working on this course project. The deliverables listed are a Flutter app covering several screens, including login, registration, a chat interface, document and task management views, and a user profile and settings section. Additional requirements include integrating Firebase Cloud Messaging so the app can receive push notifications, handling deep links so tapping a notification opens the relevant screen, caching the last ten chat sessions locally when offline, and supporting profile picture uploads from the camera or photo gallery. The prerequisites listed are Android Studio Hedgehog or later, Android SDK version 26 (Android 8.0) or higher, and Flutter SDK version 3.x. The README provides commands for running the app on an Android device or emulator, and for building a release APK or an app bundle for the Play Store. It also includes brief Firebase setup steps, which involve downloading a google-services.json configuration file from the Firebase console and placing it in the correct directory. The expected course demo involves showing the app running on both an Android emulator and an iOS simulator from the same codebase, demonstrating a full chat session with streaming AI responses, showing a live push notification on the Android device, and including at least one additional module such as documents or todos.
