# Using the atSDK with Dart

## What and why Dart ?

Dart is an open source project from Google offering a fast and multi-platform programming language. The Atsign team choose Dart as a high-level language to build proof-of-concept code. Dart proved to be a fast and reliable language to build on, and as we needed features like being able to compile to executables, the Dart team delivered.

At this point we have ported the atSDK to other languages, like Java and Python the Dart atSDK is a great place to start.

## Get Dart

Dart is available at [dart.dev](https://dart.dev/get-dart) for Windows, Linux, macOS, download and follow the instructions to install Dart. You can program in the IDE of your choice, but we can recommend [VS Code](https://code.visualstudio.com/) as it has excellent support for Dart, download install VS Code then install the Dart extension.
