title: Jetpack Compose Bottom Sheet initialization error
body: <p>In Jetpack compose 1.0.0-beta01, I am calling the BottomSheetScaffold like this:</p>
  <pre><code>BottomSheetScaffold(
      scaffoldState = bottomSheetScaffoldState,
      sheetContent = { Text(&quot;&quot;) },
      sheetShape = Shapes.large,
      backgroundColor = AppTheme.colors.uiBackground,
      modifier = modifier
      
  ) { (content) }
  </code></pre>
  <p>... and getting the following error:</p>
  <blockquote>
  <p>java.lang.IllegalArgumentException: The initial value must have an associated anchor.</p>
  </blockquote>
  <p>Any tips on fixing this?</p>
