accordion_custom 0.1.0

A customizable, zero-dependency Flutter accordion with single/multiple expand modes, nested panels, a controller, keyboard navigation, and full styling.

0.1.0

• Initial release.
• AccordionCustom with a slot-based children: API and a lazy AccordionCustom.builder constructor.
• Single- and multiple-open modes via AccordionMode.
• AccordionController (a ChangeNotifier) with expand, collapse, toggle, expandAll, collapseAll, isExpanded, and expandedIndexes.
• Per-item initiallyExpanded, enabled, custom header/headerBuilder, and arbitrary content (including nested accordions).
• Per-item headerStyle/contentStyle that override the accordion-level style, so individual panels can look different.
• Full styling through AccordionHeaderStyle (background, border color/width, corner radius, padding, text style, and a rotating icon with configurable position) and AccordionContentStyle (background, padding, text style, optional divider).
• Keyboard navigation (↑/↓ between headers, Enter/Space to toggle) and Semantics for accessibility.
• Zero dependencies; pure Dart, works on every Flutter platform.
