title: What means "_" symbol in Kotlin?
body: <p>I tried to find information what it means but I didn't. Trying to understand what it does in this code:</p>
  
  <pre><code>checkBox.setOnCheckedChangeListener { _, isChecked -&gt;
              if (isChecked) {
                  // The toggle is enabled
              } else {
                  // The toggle is disabled
              }
          }
  </code></pre>
