How to change the color of the overscroll glow effect of ListView in Flutter?

Reading here for GlowingOverscrollIndicator seems like you can change the value of ThemeData.accentColor to change the overscroll glow color.

You could try with something similar to this to limit the Theme change to the ListView only

//store the current Theme to restore it later
final ThemeData defaultTheme = Theme.of(context);

Theme(
  //Inherit the current Theme and override only the accentColor property
  data: Theme.of(context).copyWith(
    accentColor: Colors.yellow
  ),
  child: ListView.builder(
      //suppose data it's an array of strings
      itemBuilder: (BuildContext context, int index) =>
          EntryItem(data[index], defaultTheme),
      itemCount: data.length,
  ),
);

//this is your class to render rows
class EntryItem extends StatelessWidget {
  const EntryItem(this.entry, this.defaultTheme);

  final String entry;
  final ThemeData defaultTheme;

  Widget _buildTiles(String entry) {
    return Theme(
      data: defaultTheme,
      child: Text(entry)
    );
  }

  @override
  Widget build(BuildContext context) {
    return _buildTiles(entry);
  }
}
