Flutter. Using Theme, how to change scroll offset color?
You need to use accentColor property of ThemeData class
The foreground color for widgets (knobs, text, overscroll edge effect, etc).
SAMPLE CODE
class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'MyApp', theme: ThemeData( brightness: Brightness.light, //Change your color here accentColor: Colors.blue, accentColorBrightness: Brightness.light, ), home: MyHomePage(), ); }}
