VCollpasiblePanel class

A collapsible panel widget that displays a header and expandable content.

VCollpasiblePanel is a reusable component that combines a VCard container with an FAccordion widget to provide a collapsible UI element. This is useful for organizing information in a compact manner, allowing users to expand/collapse sections as needed.

The panel can be initialized in either expanded or collapsed state via the isExpanded parameter. The header is always visible and clickable to toggle the content visibility. Content is displayed below the header when expanded.

Visual Structure

  • Header: The clickable title area that remains visible
  • Content: The expandable section below the header
  • Container: Wrapped in a VCard with standard padding

Parameters

  • header: The widget displayed as the collapsible panel's title/header
  • content: The widget displayed when the panel is expanded
  • isExpanded: Whether the panel is initially expanded (defaults to false)
  • key: Optional widget key

Example

VCollpasiblePanel(
  header: Text('Settings'),
  content: Column(
    children: [
      CheckboxListTile(title: Text('Option 1')),
      CheckboxListTile(title: Text('Option 2')),
    ],
  ),
  isExpanded: false,
)
