title: Find if an element with a specific property value is found in a list
body: <p>I'm trying to find a value in a list of objects in kotlin, using for it "filter", but I need to return true or false if the value is found, but filter returns me a list of object in the case of match.</p>
  
  <pre><code>t.filter { it.retailerId == value }
  </code></pre>
  
  <p>¿How I can return a boolean when I find this value in the list of objects?</p>
