Experiment 1 - Part A: Install Flutter and Dart SDK

Aim

To install Flutter and Dart SDK on your local machine.

System Requirements

Hardware Requirements

To install and run Flutter, your Windows environment must meet the following hardware requirements:

Requirement Minimum Recommended
x86_64 CPU Cores 4 8
Memory in GB 8 16
Display resolution in pixels WXGA (1366 x 768) FHD (1920 x 1080)
Free disk space in GB 11.0 60.0

Software Requirements

To write and compile Flutter code for Android, you must have the following version of Windows and the listed software packages.

Tip: You do not need to install Dart separately as the Flutter SDK includes the full Dart SDK.

Operating System

Flutter supports 64-bit version of Microsoft Windows 10 or later. These versions of Windows should include the required Windows PowerShell 5 or later.

Development Tools

Download and install the Windows version of the following packages:

  • Git for Windows 2.27 or later to manage source code.
  • Android Studio 2023.3.1 (Jellyfish) or later to debug and compile Java or Kotlin code for Android. Flutter requires the full version of Android Studio.

The developers of the preceding software provide support for those products. To troubleshoot installation issues, consult that product's documentation.

When you run the current version of flutter doctor, it might list a different version of one of these packages. If it does, install the version it recommends.

Configure a Text Editor or IDE

You can build apps with Flutter using any text editor or integrated development environment (IDE) combined with Flutter's command-line tools.

Using an IDE with a Flutter extension or plugin provides code completion, syntax highlighting, widget editing assists, debugging, and other features.

Popular options include:

Recommended: The Flutter team recommends installing Visual Studio Code 1.77 or later and the Flutter extension for VS Code This combination simplifies installing the Flutter SDK.

Procedure

Step 1: Download Flutter SDK

  1. Visit the Flutter official website.
  2. Choose your operating system (Windows, macOS, Linux).
  3. Download the Flutter SDK zip file.

Step 2: Extract Flutter SDK

  1. Extract the downloaded zip file to a desired location on your system.
  2. Add the flutter/bin directory to your system's PATH environment variable.

Step 3: Verify Installation

  1. Open a command line interface.
  2. Run the command: 
    flutter doctor
  3. Follow any additional setup instructions provided by flutter doctor.

Step 4: Install Dart SDK

  1. Dart SDK is bundled with Flutter, so no separate installation is required.
  2. Verify Dart installation by running: 
    dart --version

Conclusion

You have successfully installed Flutter and Dart SDK on your machine. You are now ready to start developing Flutter applications.
