Usage: dart2js [options] dartfile

Compiles Dart to JavaScript.

Common options:
  -o<file> or --out=<file>
      Generate the output into <file>. If not specified, the output
      goes in a file named out.js.

  -c or --checked
      Insert runtime type checks, and enable assertions (checked
      mode).

  --minify
      Generate minified output.

  --disallow-unsafe-eval
      Disable dynamic generation of code in the output. Use this
      option when you want the generated JavaScript to satisfy CSP
      restrictions. For more information, see An Introduction to
      Content Security Policy.

  -h or --help
      Display help. (Use -vh for information about all options.)
