Flutter Developer for Mobile App (Drupal 10 Backend)

We are looking for a Flutter developer to build a mobile application (iOS & Android) for our system, a platform powered by Drupal 10 backend. The app will be primarily for clients to view offers, favorite offers, follow stores, and manage their profile.

Key Responsibilities:
_ Develop a Flutter mobile app (iOS and Android) that communicates with a Drupal 10 backend via REST API in JSON Format and OAuth2 authentication.
_ Implement user registration and login using Drupal accounts, including OAuth2 access token authentication.
_ Display offers fetched in JSON format from a view display (REST Export display)
_ Fetch and display all stores, branches, offers, and announcements from the backend.
_ Implement push notifications for new offers using stored user push tokens. (Fire base account already available and configured)
_ Implement category and subcategory filtering using backend API endpoints.
_ Keep the app synced with Drupal, including updating offers when the user changes preferred location/region.
_ Follow best practices for Flutter development, performance optimization, and clean UI/UX.

Note: The system is already done on Drupal 10 and working 100% so all you have to do is:
1. Copy the same design from the web interface of each page (around 9 pages)
2. All logic, filtering, algorithm based on user preferences like country, region, category, and subcategory... are done from the Drupal Side and all you have to do is fetch the result and display them in the app.

What You’ll Work With:
_ Backend: Drupal 10, Simple OAuth module, JSON REST API (custom Rest Export Views).
_ Frontend: Flutter (iOS & Android)
_ Features include login, registration, push notifications, dynamic content fetching, and local caching where applicable.
_ Splash screen, login screen, register screen, change password screen, login using Facebook/Apple/Google.

Requirements:
_ Experience in Flutter development and Dart programming.
_ Familiarity with consuming REST APIs and OAuth2 authentication in mobile apps.
_ Experience building apps that interact with CMS backends (Drupal preferred).
_ Ability to implement push notifications and handle dynamic content updates. (The app concept is based on sending Push notifications its users)
_ Clean, maintainable, and well-documented code.

Deliverables:
_ Fully functional Flutter mobile app compatible with Android and iOS.
_ Full Source code, properly structured and documented.
_ Integration with Drupal 10 backend using provided APIs.

It is a new business with low budget so we need a good looking basic app for now and when the business will generate revenues, we will expand it with lots of more features.
