title: Finding the sum of all values in a List of maps in Flutter
body: <p>So I have a List of Maps of two dynamic variables.</p>
  <pre><code> [{Title: product 1, Item Score: 87.3, Characters: 72, Image Count: 6},
  
   {Title: product 2, Item Score: 85.1, Characters: 56, Image Count: 2}]
  </code></pre>
  <p>How would I add up all of them item scores? There are more items than this in the full file.</p>
