Flutter. Using Theme, how to change scroll offset color?

Question

For beginning I am very sorry for my English. I am not a native speaker and additionally this is my first post in this language. I will be grateful for your understanding. Here is what I mean:

How to set scroll color other than this green in dark theme? I can't do this.

Below is my code:

 theme: ThemeData(
    brightness: Brightness.dark,
    primaryColor: Colors.pink,
    backgroundColor: Colors.grey[900],
    textSelectionColor: Colors.pink,
    textSelectionHandleColor: Colors.pink[700],  

    textTheme: TextTheme(
      body1: TextStyle(color: Colors.white),
    ),

  ),

Thank you in advance for your help :)

Solution

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(),
    );
  }
}
