## Setting up your environment
## Dependencies

### Downloading and installing the Dart SDK
Flutter depends on the following tools being available in your environment. These are commonly already available on Mac and Linux.

To get started, you need to install the Dart SDK.
Flutter requires Dart SDK 1.12.2 or greater.

To install the [Dart SDK](https://www.dartlang.org/downloads/):

- Mac:
- `brew tap dart-lang/dart && brew install dart`, or, if you don't use
homebrew, grab the [latest stable channel build](https://www.dartlang.org/downloads/archive/)
- Linux: See [www.dartlang.org/downloads/linux.html](https://www.dartlang.org/downloads/linux.html)
- Windows: Stay tuned, Windows support is planned.

### Checking your PATH

Ensure that the `pub` executable is in your `PATH`.

Run `pub --version` on the command line. If that command
is not found, you will need to add `DIRECTORY_WHERE_DART_SDK_IS_LOCATED/bin`
to your PATH.

For example:

```
$ export PATH=<DART_SDK_DOWNLOAD_LOCATION>/bin:$PATH
```
* bash, mkdir, rm
* git

The first time you type 'git' on mac, it shows a dialog about the command-line developer tools. Unclear if we need to walk people through this?

I guess I'm not supposed to be on alpha? Moved to flutter/flutter@7a2c38a and i'm continuing OK.

The first time you do this will take a few seconds as Flutter will first download the Dart SDK then precompile itself.
Subsequent runs should be much faster.

Flutter will only need to do these steps after subsequent flutter upgrade commands?
