title: Laravel custom validation message
body: <p>I'm using laravel 5.4 to make a custom form validation. But why is the custom error message isn't displayed?</p>
  
  <pre><code>   Validator::extend('myCustomeValidator', function ($attribute, $value, $parameters, $validator) {
          //some code here
          return false;
      });
  
      return Validator::make($data, [
          'myField' =&gt; 'myCustomeValidator',
      ]);
  </code></pre>
  
  <p>and added the following to the file : <code>ressources\lang\en\validation.php</code> as the documentation advises:</p>
  
  <pre><code>    'custom' =&gt; [
          'myField' =&gt; [
              'myCustomeValidator' =&gt; 'You made an error.',
          ],
      ],
  </code></pre>
  
  <p>The error is correctly triggered but instead of my custom error message, I get this:</p>
  
  <blockquote>
    <p>validation.my_custome_validator</p>
  </blockquote>
  
  <p>What am I missing?</p>
