AddonAccessor class abstract

A class that provides access to data in the BuildContext that is available from every place where the Addon API gives access to a BuildContext.

Classes that hold or build widgets within an addon implement a static access field that returns an instance of this class.

These classes include subclasses of AddonLayerEntry, subclasses of AddonControlSection, HomePageComponent and AddonDescription.

Subclasses of this class such as AddonLayerAccessor and UseCaseAccessor introduce additional data that can be accessed only in specific contexts.

Make sure to use the access field on the class which actually builds the widgets you want to access the data in. Otherwise the data might not be available in the BuildContext.
