title: How can I show the indicator in a VerticalScroller (android developer compose)?
body: <p>Working on understanding android <code>jetpackcompose</code> in Android Studio 4.0 Canary.</p>
  
  <p>I have a simple <code>jetpackcompose</code> setup with a <code>VerticalScroller</code> like this:</p>
  
  <pre><code>@Composable
  fun MyScreenContent(appState: AppState = AppState())
  {
  
      FlexColumn{
  
  
         flexible(flex = 1f){
             VerticalScroller {
               Column {
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
                  CardDemo()
              }
          }
      }
   }
  }
  </code></pre>
  
  <p>It scrolls perfectly, but I want a <code>scrollindicator</code> which shows me how far my list has scrolled, how do I turn that on, can't find any <code>ScrollIndicator</code> (i.e.) component to include.</p>
  
  <p>Ref. to <code>RecyclerView</code> in a non composable setup (xml) where the <code>scrollindicator</code> is visible:</p>
  
  <pre><code>            &lt;androidx.recyclerview.widget.RecyclerView
                  android:id="@+id/station_list"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  android:background="@color/recyclerview_background_color"
                  android:clipChildren="true"
                  android:clipToPadding="false"
                  android:fadeScrollbars="false"
                  android:paddingLeft="0dp"
                  android:paddingRight="0dp"
                  android:scrollbarSize="4dp"
                  android:scrollbarThumbVertical="@color/colorPrimary"   &lt;---
                  android:scrollbars="vertical"                          &lt;---
                  android:visibility="visible"
                  app:isGone="@{!hasStations}"
                  app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
                  app:layout_constraintStart_toStartOf="parent"
                  tools:context="no.rogo.projectfk303.ui.activities.MainActivity"
                  tools:listitem="@layout/list_item_station" /&gt;
