C to Dart: A Comprehensive Guide

Introduction

Transitioning from C to Dart can be a rewarding experience for developers. Dart, developed by Google, is a versatile language used primarily for building mobile, desktop, and web applications. This article will guide you through the process of moving from C to Dart, highlighting key differences and similarities. Why Transition from C to Dart?

1. Modern Syntax: Dart offers a more modern and readable syntax compared to C.
2. Cross-Platform Development: Dart is the backbone of Flutter, enabling cross-platform app development.
3. Strong Community Support: Dart has a growing community and extensive documentation.

Key Differences Between C and Dart

1. Syntax and Structure

• C: Procedural language with a focus on functions.
• Dart: Object-oriented language with classes and objects.

2. Memory Management

• C: Manual memory management using malloc and free.
• Dart: Automatic garbage collection.

3. Libraries and Packages

• C: Limited standard libraries.
• Dart: Rich set of libraries and packages available through pub.dev.

Similarities Between C and Dart

• Control Structures: Both languages use similar control structures like if-else, for, and while loops.
• Basic Data Types: Both support basic data types like int, double, and char (String in Dart).

How to Convert C Code to Dart

Example: Hello World C Code:

#include <stdio.h>
