Instructor: Using the Chocolatey package manager, we can install the Dart SDK by running choco install dart-sdk. Alternatively, you can install the Dev Channel version by passing the pre flag. To upgrade a pre-existing Dart installation, run choco upgrade dart-sdk.
Restart your command prompt in order to confirm your Dart installation. Confirm Dart is properly installed by typing the dart command and passing the version flag.
In your working folder, create a pubspec.yaml file. A pubspec file contains metadata and configuration related to a Dart project. We will enter the minimum information about our project, such as a name, description, and an author.
All starting files go in a bin folder. Let's create one containing a main.dart file. In this file, we will define a top-level function called main. Dart requires this function to start our application. Save the file and run. This completes the lesson.
