## What it is
The Dart SDK is the open-source toolkit for the Dart programming language, including the Dart VM with JIT and AOT compilation, JavaScript and WebAssembly compilers, static analysis, and core libraries. It powers multi-platform app development, most notably as the language behind Flutter.

## Use cases
- build cross-platform mobile and desktop apps
- compile dart code to javascript or webassembly for the web
- write command-line tools and server backends
- learn a strongly typed language with null safety
- set up a dart development environment with the sdk
- publish packages to pub.dev

## When to choose
- you are building Flutter apps or Dart-based tooling
- you want one language compiling to native, JS, and Wasm targets
- you need hot reload and strong static analysis for fast iteration

## When to avoid
- your project is already committed to another ecosystem like JavaScript, Python, or Go
- you need a language with a broader general-purpose package ecosystem than pub.dev
- you only need lightweight scripting where a VM SDK install is overkill
