build({required ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data}) → Widget: Builds the widget. If there are dynamic keys on the data object, and the widget is not a PreferredSizeWidget, then the returned widget will be wrapped by a stateful widget that will rebuild if any of the dynamic args change in value.
inherited
buildCustom({ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data, Key? key}) → Widget: Custom builder that subclasses must override and implement to return the actual Widget to be placed on the tree.
override
getChild(JsonWidgetData? data, {int index = 0}) → JsonWidgetData: Returns a non-null child for widgets that must always have child widgets. This allows the widget to be built and rendered even if the child is missing.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
remove(JsonWidgetData data) → void: Called when a JSON widget is removed from the tree due to a conditional. Custom widgets may need to implement this to clean up values that may have been placed on the JsonWidgetRegistry by the widget.
inherited
toString() → String: A string representation of this object.

fromDynamic(dynamic map, {JsonWidgetRegistry? registry}) → JsonAssetImageBuilder?: Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
