title: Flutter: How to specify exact character to appear during email validation
body: <p>In my email validation, I want to make it mandatory that the user should use the full <code>.com</code> extension in there email field. Currently, the way I have my <strong>RegExp</strong> it only accepts starting with <code>.c</code> or <code>.o</code> or <code>.m</code> instead of throwing an error if there in no exact match with <code>.com</code></p>
  <p>How do I go about resolving this?</p>
  <p>Here is my RegExp</p>
  <pre><code>final RegExp emailValidatorRegExp = RegExp(r&quot;^[a-zA-Z0-9.]+@[a-zA-Z0-9]+.com&quot;);
  </code></pre>
