title: Flutter - How to do a tick box filter for a list to narrow down search
body: <p>I am very new to flutter and still learning. I am struggle on how to create a filter for a list of cars. E.g. tick a box to only show red cars. </p>
  
  <p>I do a little bit of searching but I can't seem to figure out how to do it. I did see a "where" method but struggling to make sence of it.  </p>
  
  <p>What is the the best way of doing this and can you please point me in the right direction. Can't get my head about this one.</p>
