Introduction

Flutter is a popular framework for developing cross-platform mobile applications. Whether you’re a beginner or an experienced developer, this step-by-step guide will walk you through the installation process of Flutter on both Windows and Mac operating systems. By the end of this tutorial, you’ll have a fully set up Flutter development environment ready to start building your own mobile apps.

System Requirements

Before diving into the installation process, ensure that your system meets the following requirements:

  • Windows:
    • Operating System: Windows 7 SP1 or later (64-bit)
    • Disk Space: 2.8 GB (excluding the space required for IDEs/tools)
    • Tools: Git for Windows
  • Mac:
    • Operating System: macOS (64-bit)
    • Disk Space: 2.8 GB (excluding the space required for IDEs/tools)
    • Tools: Git

Make sure you have administrative privileges on your machine to install the required dependencies.

Installing Flutter on Windows

Follow these steps to install Flutter on a Windows system:

Step 1: Downloading Flutter SDK

To begin, download the Flutter SDK from the official Flutter website (https://flutter.dev). You can choose either the stable release or the beta release, depending on your preference. Once downloaded, extract the ZIP file to a location of your choice.

Step 2: Setting up Flutter Environment Variables

Next, you need to add the Flutter SDK path to the system’s environment variables. Here’s how you can do it:

  1. Open the Start menu and search for “Environment Variables.”
  2. Click on “Edit the system environment variables.”
  3. In the “System Properties” window, click on the “Environment Variables” button.
  4. Under the “System variables” section, select the “Path” variable and click on “Edit.”
  5. Click on “New” and add the path to the Flutter SDK’s “bin” directory (e.g., C:\flutter\bin).
  6. Click “OK” to save the changes.

Step 3: Installing Flutter Dependencies

Flutter requires a few additional dependencies to work properly. Open a command prompt and run the following command to install them:

flutter doctor

This command will check for missing dependencies and prompt you to install them. Follow the instructions provided by the Flutter CLI to install any missing components.

Step 4: Verifying Flutter Installation

To ensure that Flutter is installed correctly, run the following command in the command prompt:

flutter doctor

This command will display a report of the status of your Flutter installation. If everything is set up correctly, you should see “No issues found!” along with a list of connected devices (e.g., emulators or physical devices).

Installing Flutter on Mac

Here’s how you can install Flutter on a Mac:

Step 1: Downloading Flutter SDK

Start by downloading the Flutter SDK from the official Flutter website (https://flutter.dev). Choose either the stable release or the beta release, depending on your preference. Once downloaded, extract the ZIP file to a location of your choice (e.g., your home directory).

Step 2: Setting up Flutter Environment Variables

To set up Flutter environment variables on a Mac, follow these steps:

  1. Open Terminal.
  2. Run the following command to open the .bash_profile file:
open -e .bash_profile
  1. Add the following line to the file, replacing [PATH_TO_FLUTTER_DIRECTORY] with the actual path to the Flutter SDK directory:
export PATH="[PATH_TO_FLUTTER_DIRECTORY]/flutter/bin:$PATH"
  1. Save the changes and close the file.

Step 3: Installing Flutter Dependencies

Flutter requires a few additional dependencies to function properly. In Terminal, run the following command:

flutter doctor

This command will check for any missing dependencies and guide you through the installation process.

Step 4: Verifying Flutter Installation

To verify that Flutter is installed correctly on your Mac, run the following command in Terminal:

flutter doctor

If everything is set up correctly, you should see “No issues found!” along with a list of connected devices.

Troubleshooting Tips

Sometimes, during the installation process, you may encounter common issues. Here are a few troubleshooting tips to help you resolve them:

Common Installation Issues and Solutions

  1. Problem: Flutter doctor reports a missing dependency.
    • Solution: Follow the instructions provided by the Flutter doctor to install the missing component.
