title: Passing command line arguments to a flutter app
body: <p>Is <a href="https://pub.dartlang.org/packages/args" rel="noreferrer">package:args</a> ArgParser compatible with flutter apps? I see on Github that it is used several times in some <a href="https://github.com/flutter/flutter/blob/df675f45ee408389782fd404849475979c125c3a/packages/flutter_tools/bin/fuchsia_builder.dart#L51" rel="noreferrer">Flutter tools</a>, but I'm not sure it's used in any of the sample apps.</p>
  
  <p>If it is not compatible, is there another way to pass configuration options to my app at compile time as part of its build rule?</p>
