TAccordion class

A customizable Accordion (ExpansionTile) widget for Flutter UI.

The TAccordion provides a collapsible panel that expands or collapses when tapped, revealing or hiding the provided child widget.

Features:

  • Customizable title and trailing icon
  • Optional border and background decoration
  • Animated icon rotation to indicate expansion
  • Supports dynamic theming via TThemeManager
  • Optional divider at the bottom of the expanded content

Parameters:

  • title: The main label displayed in the accordion header.
  • child: The widget displayed when the accordion is expanded.
  • initiallyExpanded: Whether the accordion starts in expanded state.
  • borderColor: Color of the bottom divider when expanded (optional).
  • borderWidth: Thickness of the bottom divider when expanded (default is 0.5).
  • showDivider: Whether to display a divider below the child content (default is true).
  • enableDecoration: If true, wraps the accordion with a decorated container (e.g., border, background color).
  • decoration: Custom BoxDecoration for the container (used if enableDecoration is true).
  • trailing: Custom trailing widget (e.g., custom arrow icon). Defaults to an animated Icons.keyboard_arrow_up.
  • titleStyle: Custom TextStyle for the title.
  • padding: Reserved for future use (currently unused).

Example:

TAccordion(
  title: "Order Details",
  child: Column(
    children: [
      Text("Order ID: 12345"),
      Text("Status: Shipped"),
    ],
  ),
  initiallyExpanded: false,
  enableDecoration: true,
  trailing: Icon(Icons.expand_more),
)

Notes:

  • The trailing icon automatically rotates when expanded/collapsed.
  • The widget integrates with TThemeManager for dynamic theming support.
  • padding is included for API consistency but currently not applied.
