Getting Started with Flutter – Step-by-Step Guide

Part 2: Getting Started with Flutter – Step-by-Step Guide

Introduction

Now that you know why Flutter is a great choice for mobile app development, let’s dive into setting up your Flutter development environment and creating your first Flutter app.

Step 1: Install Flutter

Before you can start developing with Flutter, you need to install the Flutter SDK on your machine.

1. Download Flutter SDK

   • Visit the Flutter official website and download the SDK for your operating system (Windows, macOS, or Linux).

2. Extract the Files

   • Extract the downloaded file to a suitable location (e.g., C:\flutter on Windows or ~/flutter on macOS/Linux).

3. Add Flutter to the System Path

   • On Windows: Add C:\flutter\bin to your system PATH.
   • On macOS/Linux: Add export PATH="$PATH:pwd/flutter/bin" to your ~/.bashrc or ~/.zshrc.

Step 2: Install an IDE

To write and debug Flutter applications, you need an Integrated Development Environment (IDE). The most popular choices are:

• Android Studio (Recommended for full Android support)
• Visual Studio Code (Lightweight and fast)

After installing your IDE, install the Flutter and Dart plugins.

Step 3: Verify the Installation

Run the following command in your terminal to check if Flutter is installed correctly:

flutter doctor

This command checks for missing dependencies and provides instructions to fix any issues.

Step 4: Create Your First Flutter App

Run the following command to create a new Flutter project:

flutter create my_first_app

Navigate to the project folder:

cd my_first_app

To run your app on an emulator or a connected device, use:

flutter run

Step 5: Understanding the Project Structure

A Flutter project contains several important folders:

• lib/ – The main directory where your Dart code lives.
• pubspec.yaml – The configuration file for dependencies and assets.
• android/ & ios/ – Platform-specific files for Android and iOS.
