ScrollbarThemeData class

Defines default property values for descendant MacosScrollbar widgets.

Descendant widgets obtain the current ScrollbarThemeData object with ScrollbarTheme.of(context). Instances of ScrollbarThemeData can be customized with ScrollbarThemeData.copyWith.

Typically the ScrollbarThemeData of a ScrollbarTheme is specified as part of the overall MacosTheme with MacosThemeData.scrollbarTheme.

All ScrollbarThemeData properties are null by default. When null, the MacosScrollbar computes its own default values.

• MacosThemeData, which describes the overall theme information for the application.
