title: Jetpack Compose Textfield OnFocusChangeListener
body: <p>I have a standard Textfield and I wanna know when user sets focus in it. is there a way to do that?</p>
  <p>I tried to set clickable modifier to trigger the event when somebody clicks on it but looks like it doesn't work with TextField:</p>
  <pre><code>modifier = Modifier
              .clickable {
                  shouldShowSearchKeyBoard.value = true
              },
  </code></pre>
