title: Why is 'androidx.constraintlayout:constraintlayout' omittable?
body: <p>I notice that I can comment out <code>implementation 'androidx.constraintlayout:constraintlayout:2.0.4'</code> without any errors though I use ConstraintLayout in my app.</p>
  <pre><code>dependencies {
      implementation 'androidx.appcompat:appcompat:1.2.0'
      implementation 'com.google.android.material:material:1.3.0'
      // implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
      implementation 'androidx.navigation:navigation-fragment:2.3.3'
  }
  </code></pre>
  <p>Why is it ok? Does the com.google.android.material library also contain constraintLayout?</p>
