Flutter : How to add scroll indicator in ListView

Is there any way to show the scroll indicator on the ListView?

Here is my basic code:

ListView.builder(
  itemCount: 50,
  itemBuilder: (context, index) => ListTile(title: Text("Item= ${index + 1}"),),
)

Thanks to Günter Zöchbauer.

You can wrap your ListView in Scrollbar

Scrollbar(
    child: ListView.builder(
      itemCount: 50,
      itemBuilder: (context, index) => ListTile(title: Text("Item= ${index + 1}"),),),
)

I think better to use CupertinoScrollbar instead of Scrollbar. CupertinoScrollbar is can touch and scroll to the bottom..

Ex:

 CupertinoScrollbar(
            child: ListView.builder(...),

Or

Scrollbar(
    child: ListView.builder(...),

In this code: An example of how to show in ListView

child: Scrollbar( 
   child: ListView.builder(
   padding: EdgeInsets.all(5),
   itemCount: snapshot.data.length,
    physics: BouncingScrollPhysics(),
    itemBuilder: (context, index) {
      return generateColum(snapshot.data[index], index);
    }),
 ),

You can implement this designer scrollbar library :

1. draggable_scrollbar

2. alphabet scrolling

OR

You can wrap ListView in Scrollbar widget

Scrollbar(
    child: ListView.builder(...),
)
