title: Pick main color from picture
body: <p>I'm new to Dart/Flutter framework and I'm still exploring their possibilities.</p>
  
  <p>I know in Android it's possible to take a picture and extract the main color value from it programmatically. (<a href="https://stackoverflow.com/questions/8471236/finding-the-dominant-color-of-an-image-in-an-android-drawable?utm_medium=organic&amp;utm_source=google_rich_qa&amp;utm_campaign=google_rich_qa">Android example</a>)</p>
  
  <p>I wonder, how would this be achieved in pure Dart? I would like it to be compatible with both iOS and Android operating system.</p>
