AccordionTheme class

Theme configuration for Accordion, AccordionItem, and AccordionTrigger widgets.

AccordionTheme provides comprehensive styling options for all accordion-related widgets, including animation timing, spacing, colors, and iconography. It allows for consistent accordion styling across an application while still permitting per-instance customization.

Used with ComponentTheme to apply theme values throughout the widget tree.

Example:

ComponentTheme<AccordionTheme>(
  data: AccordionTheme(
    duration: Duration(milliseconds: 300),
    curve: Curves.easeInOut,
    padding: 20.0,
    arrowIcon: Icons.expand_more,
    arrowIconColor: Colors.blue,
  ),
  child: MyAccordionWidget(),
);
