flutter_adaptive_cards_extend_fs library

Classes

AdaptiveTappable: Wraps any element subtree to honor JSON selectAction taps in custom renderers.
AdaptiveTappableState: State for AdaptiveTappable that resolves and invokes selectAction.
BarChartLayout: Resolved layout values for bar chart types.
BarChartLayoutSection: HostConfig chartsLayout.bar section.
ChartsLayoutConfig: HostConfig chartsLayout section for chart element dimensions and chrome.
ChildStyler: Pushes container style and horizontalAlignment inheritance to descendants via scoped resolver.
FadeAnimation: One-shot fade-out wrapper that removes child when the animation completes.
FadeAnimationState: State object for FadeAnimation; not intended for direct host use.
FullCircleClipper: Rectangular clipper used for person-style image masks in card elements.
LineChartLayout: Resolved layout values for Chart.Line rendering.
LineChartLayoutSection: HostConfig chartsLayout.line section.
PieChartLayout: Resolved layout values for Chart.Pie.
PieChartLayoutSection: HostConfig chartsLayout.pie / chartsLayout.donut section.
SeparatorElement: Applies Adaptive Cards spacing and optional separator above child content in custom elements.
Tuple<A, B>: Lightweight two-value holder for internal/extension helpers.
UUIDGenerator: Shared id generation for elements missing author-supplied id values.

Enums

BarChartAlignmentToken: Token for bar group alignment (maps to fl_chart BarChartAlignment).

Mixins

AdaptiveActionMixin<T extends AdaptiveElementWidgetMixin>: Static action label/tooltip from baseline JSON for simple action widgets.
AdaptiveActionStateMixin<T extends AdaptiveElementWidgetMixin>: Reactive action label, tooltip, and enabled state from merged baseline + overlays.
AdaptiveElementMixin<T extends AdaptiveElementWidgetMixin>: Shared element identity and background-image helpers for adaptive widgets.
AdaptiveElementWidgetMixin: Contract for adaptive element widgets that expose JSON and a stable id.
AdaptiveInputMixin<T extends ConsumerStatefulWidget>: Shared input overlay, validation, and value-changed-action behavior for input widgets.
AdaptiveTextualInputMixin<T extends ConsumerStatefulWidget>: Marker mixin for text-like inputs that share AdaptiveInputMixin behavior.
AdaptiveVisibilityMixin<T extends AdaptiveElementWidgetMixin>: Subscribes to merged isVisible and exposes setIsVisible for hosts.
ProviderScopeMixin<T extends StatefulWidget>: Reads card-scoped Riverpod providers from the enclosing ProviderScope.

Functions

backgroundImageSpecified(Map element) → bool: Returns whether element defines a usable backgroundImage value.
firstCharacterToLowerCase(String s) → String: Lowercases only the first character of s.
generateAdaptiveWidgetKey(Map aMap) → ValueKey<String>: Deterministic ValueKey for the adaptive wrapper widget ({id}_adaptive).
generateWidgetKey(Map aMap, {String? suffix}) → ValueKey<String>: Deterministic ValueKey for an input/control from element JSON.
generateWidgetKeyFromId(String id, {String? suffix}) → ValueKey<String>: Deterministic ValueKey from a resolved element id.
getDayOfMonthSuffix(int n) → String: Returns the English ordinal suffix (st, nd, rd, th) for day n.
idIsNatural(Map aMap) → bool: True when id was author-supplied rather than auto-generated at card load.
injectIds(dynamic data) → void: Ensures every typed JSON node has an id before rendering; call on a copy, not host-owned maps.
loadErrorMessage({required BuildContext context, String? errorMessage, bool showError = false}) → Widget: Builds the validation error text below an input when showError is true.
loadId(Map aMap) → String: Resolves element id from JSON; generates one if missing (normally pre-injected).
loadLabel({required BuildContext context, String? label, bool isRequired = false}) → Widget: Builds the label row above an input using HostConfig label styles.
parseHexColor(String? colorValue) → Color?: Parses #RRGGBB or #AARRGGBB hex strings into Color.
parseHostConfigColor(dynamic value) → Color?: Parses HostConfig hex colors (#RRGGBB or #AARRGGBB); returns null when invalid.
parseIsVisible(Object? value) → bool: Parses Adaptive Card isVisible values from JSON (bool, string, or absent).
parseMinHeight(dynamic rawMinHeight) → double?: Parses the minHeight property from the Adaptive Cards JSON, supporting both pixel values (e.g. "240px") and raw integer/double values.
parseTextString(String text, {String? locale}) → String: Expands Adaptive Cards {{DATE(...)}} and {{TIME(...)}} templates in display text.
