Looking for feedback and improvement suggestions for BudgetBudy (Flutter expense tracker)

[devaldaki3]

Hi everyone 🙏
I’ve built BudgetBudy, a Flutter-based personal finance and expense tracking app with features like offline storage, category-wise expenses, and a Khatabook-style party ledger.

Nice work on BudgetBudy it’s a solid foundation for a Flutter finance app, especially with offline-first support.

A few suggestions after reviewing the project:
Architecture & Structure
The app would benefit from a clearer separation between UI, business logic, and data layers. Consider moving toward a cleaner architecture (feature-based folders or MVVM-style separation) to improve scalability as features grow.

State Management
Provider works fine here, but as the app expands, Riverpod or Bloc could make state handling more predictable and testable. This would also help reduce widget rebuilds.

Database Layer
Abstracting SQLite logic behind a repository layer would make the code easier to maintain and test. It also prepares the app for a future backend or cloud sync if you decide to add one.

UI/UX Improvements
The functionality is strong, but the UI could be more intuitive:

Clearer empty states
Better visual distinction between credit and debit entries
More consistent spacing and typography
Features to Consider
Export data to CSV or PDF
Monthly budget limits with alerts
Basic analytics like spending trends per category
