body: <p>How do I perform a transaction in dart mysql1.
  I tried doing this,</p>
  <pre><code>await pool.transactional((conn) async {});
  
  </code></pre>
  <p>But the key wait pool is showing this error
  <strong>Undefined name 'pool'.
  Try correcting the name to one that is defined, or defining the name.dartundefined_identifier</strong></p>
