Using Sublime Text 2 as an IDE

You can download Sublime Text free of cost for evaluation, however, for continued use, a license must be purchased from http://www.sublimetext.com/.

Tim Armstrong from Google developed a Dart plugin for Sublime Text, which can be downloaded from GitHub at https://github.com/dart-lang/dart-sublime-bundle, or you can find it in the code download with this book. The easiest way to get started is to install the Package Control plugin first by following the instructions at https://sublime.wbond.net/installation#st2.

In Sublime Text, press Ctrl + Shi ft + P (Windows or Linux) or Cmd + Shift + P (OS X; this goes for all the following commands), click on Install Package to choose that option, and then click and choose Dart to install the plugin. Any Dart file you then open shows the highlighted syntax, matching brackets, and so on.

Also, click on Menu Preferences, Settings, and then on User and add the path to your dart-sdk as the first line in this JSON file:

{
"dartsdk_path": "path\to\dart-sdk",
…
}

If you want to manually install this plugin, copy the contents of the dart-sublime-bundle-master folder to a new directory named Dart in the Sublime packages directory. This directory has different locations on different OS. They are as follows:

The plugin has a number of code snippets to facilitate working with Dart, for example, typing lib expands the library statement. Other snippets include imp for import, class for a class template, method for a method template, and main for a main() function. Typing a snippet in the pop-up window after pressing Ctrl + SHIFT + P lets you see a list of all the snippets. Use Ctrl + / to (un)comment the selected code text.

The plugin has also made a build system for you. Ctrl + B will invoke the dartanalyzer and then compile the Dart code to JavaScript with the dart2js compiler, as shown in the following screenshot. Editing and saving a pubspec.yaml file will automatically invoke the pub get command.
