Calculator

1).A Basic Calculator Application is a simple yet essential tool designed to perform fundamental
arithmetic operations such as addition (+), subtraction (−), multiplication (×), division (÷), and percentage (%).

This calculator provides users with an easy-to-use interface that allows quick and accurate calculations,
reducing manual effort and human error.

2).The main objective of the Basic Calculator app is to offer a smooth, responsive, and user-friendly experience for
performing everyday mathematical operations. It can be used by students, professionals, or anyone who needs to perform
quick calculations in their daily routine.

3).In the context of software development, building a calculator is a foundational project that helps developers
understand key programming concepts such as user interface (UI) design, state management, event handling, and expression
evaluation. The simplicity of the application makes it an ideal starting point for learning logical and functional
programming in languages like Dart (Flutter).
