title: Unresolved reference: viewModelScope - Kotlin Android
body: <p>I try to add viewModelScope to a basic viewModel but android studio doesn't recognize it.</p>
  
  <p>I tried to change my gradle build file with some solution I found but nothing works.</p>
  
  <p>Here an extract of my build.gradle app</p>
  
  <pre><code>implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0-alpha01"
  implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.2.0-alpha01"
  implementation "androidx.lifecycle:lifecycle-viewmodel-savedstate:1.0.0-alpha01"
  kapt "androidx.lifecycle:lifecycle-compiler:2.2.0-alpha01"
  </code></pre>
  
  <p>When I type viewModelScope in my viewModel it say <code>Unresolved reference: viewModelScope</code>.</p>
