Calculator App

A simple yet functional calculator application built using Android, Kotlin, and Jetpack Compose. This app demonstrates the use of modern Android development best practices, including MVVM (Model-View-ViewModel) architecture and Clean Architecture principles.

Features

• Basic arithmetic operations: addition, subtraction, multiplication, and division.
• Clear input and reset operations.
• Responsive UI with Jetpack Compose.
• Optimized for performance and scalability using Clean Architecture and MVVM.
• User-friendly design, offering smooth interactions.

Tech Stack

• Language: Kotlin
• UI: Jetpack Compose
• Architecture: MVVM (Model-View-ViewModel)
• Design Principles: Clean Architecture
• Build Tool: Gradle

Architecture

This project is structured based on the MVVM pattern and follows Clean Architecture principles:

1. UI Layer:

   • Built using Jetpack Compose, handling all the interactions and displaying the data from the ViewModel.
   • Uses State in Compose for reactive UI updates.

2. Domain Layer:

   • Contains business logic in use cases.
   • Encapsulates the core functionality of the app (e.g., performing calculations).

3. Data Layer:

   • Manages data operations. In this case, it processes the inputs and performs calculations.

4. ViewModel:

   • Acts as a mediator between the UI and domain layer.
   • Stores the UI state and provides data to the Compose UI in a lifecycle-aware manner.
