Data structures

A data structure is a particular way storing and organizing data in a computer for efficient access and modification. Data structures are designed for a specific purpose. Examples include arrays, linked lists, and classes.

https://github.com/uchamod/flutter-notepro

A simple and efficient to-do and note-taking app developed using Flutter. This app allows users to create, manage, and organize tasks and notes with ease. Data is securely stored locally using Hive, ensuring quick access and offline functionality. The project highlights the use of Flutter for creating intuitive user interfaces and Hive.
