Efficient transaction management and tracking.

Always wanted to create this application where i can maintain my expenses and subs with different banking cards and accounts.

I will be adding more features which are written down in projects notebook

I choose Provider as a state management solution for this application because of the simplicity and its a small project so no need to go overboard with MVVM which i mainly use in my large apps

Used supabase because i just like working with it and have knowledge of postgresQL. Also don't need to worry about auth and storage as it includes all the necessary features.

Features

• User Authentication: Secure user authentication powered by Supabase. Users can sign up and sign in to manage their data.
• Transaction Management:
  • Ability to record and manage financial transactions.
  • Support for adding descriptions, amounts (using Decimal for precision), and associated stores.
  • Receipt Image Uploads: Users can attach receipt images to their transactions.
• Item Management: Generic dialogs (ManageItemsDialog, ManageItemsBottomSheet) for creating, reading, updating, and deleting (CRUD) various items like stores or categories, promoting reusable UI components.
• State Management: Utilizes the Provider package with ChangeNotifier to efficiently manage the application's state, particularly for authentication (AuthProvider) and transaction data (TransactionProvider).

Architecture and Logic

The application follows a modular architecture using the Provider pattern for state management:

• lib/auth_provider.dart: Handles all user authentication logic, including sign-up, sign-in, and managing the current user session with Supabase. It exposes the authentication state to the rest of the app via a ChangeNotifier.
• lib/transaction_provider.dart (inferred): Manages the application's transaction data, likely handling creation, retrieval, updating, and deletion of transactions.
• lib/models/transaction.dart & lib/models/store.dart: Define the data structures for transactions and stores within the application.
• lib/widgets/transaction_form.dart: A key UI component for entering and modifying transaction details, showcasing "progressive-disclosure UX patterns" to allow quick logging and later refinement. It also integrates image picking for receipts.
• lib/widgets/manage_items_dialog.dart: A reusable widget designed for generic CRUD operations on various lists of items (e.g., managing stores or transaction categories).
