title: How to use dart-protobuf
body: <p>I'm considering using <a href="https://github.com/dart-lang/dart-protobuf" rel="noreferrer">dart-protobuf</a> instead of JSON in one of my projects. The problem is that the library does not provide any example of how to use it, and the tests don't really help either.</p>
  
  <p>I'm also a bit confused on how the parsing of <code>.proto</code> files would work.</p>
  
  <p>So I'm looking for a simple example of how to use this library in dart.</p>
