Keeping your Dart SDK updated is essential for performance, stability, and compatibility with modern tools. Whether you are developing Flutter applications or working with standalone Dart projects, updating the Dart SDK ensures access to the latest features and bug fixes.

This guide explains how to update Dart SDK using different methods including command line, VS Code, Android Studio, and Flutter.

What is Dart SDK?

Dart SDK is the core toolkit required to run Dart programs. It includes:

• Dart Virtual Machine (VM)
• Core libraries
• Compiler
• Command-line tools

If you are using Flutter, Dart SDK is included inside Flutter.

Check Current Dart Version

Before updating Dart SDK, check the current version:

dart --version

For Flutter users:

flutter --version

Method 1: Update Dart SDK Using Command Line (CMD)

This method is suitable for standalone Dart installations.

Windows (Chocolatey)

• Always use Flutter upgrade for Flutter projects
• Manual updates are only for standalone Dart environments
