title: SingletonComponent is missing a parent declaration
body: <p>I have just updated my android <strong>Hilt-Dagger</strong> dependences to 1.0.0-alpha03<br />
  and I figure that <strong><code>ApplicationComponent</code></strong> is <strong>deprecated</strong><br />
  and replaced with <strong><code>SingletonComponent</code></strong><br />
  but once I replace it at my code it shows up this error
  Am I need to do anything else except replacing it?</p>
  <p>Full Error</p>
