QuickMaths is a versatile Flutter application that combines a fully functional calculator with a secure cipher lab for encrypting and decrypting messages.
The app launches first to a sleek calculator screen, providing basic and advanced calculations. To access the cipher lab, users must enter a default password — 1234 — ensuring secure access to encrypted messaging features.
The cipher lab supports multiple encryption methods, maintains a real-time history of encrypted and decrypted texts, and allows theme customization. The app uses Provider for efficient state management, ensuring smooth UI updates and a responsive user experience.
