title: Dart/Flutter How to compare two TimeOfDay times?
body: <p><code>TimeOfDay</code> documentation has no comparison operator and primitive comparison does not work. My only solution that I can thinking of right now is to convert <code>TimeOfDay</code> to <code>DateTime</code> and use <code>DateTime</code>'s difference method.</p>
  <p>Does anyone have a better solution?</p>
