title: Cannot resolve symbol 'FirebaseRecyclerOptions'
body: <p>I was making a recycler view. And when I tried to add database-ui of firebase, looks like it didn't work. I got error:</p>
  <p><code>Cannot resolve symbol 'FirebaseRecyclerOptions'</code></p>
  <p>I found that it wasn't imported, and did it manually, but got error:</p>
  <p><code>Cannot resolve symbol 'firebase'</code></p>
  <p>I looked for solutions. Updated versions of all firebase dependencies to latest ones for 3 May 2022. But nothing changed.</p>
  <p>This is my dependencies:</p>
  <pre><code>dependencies {
  
      implementation 'androidx.appcompat:appcompat:1.4.1'
      implementation 'com.google.android.material:material:1.5.0'
