initialize method
Callback to initialize the Feature. This method
is called when the feature is registered and should
not be invoked directly. It should also be noted
that the registeredFeatures
map is a map of all
the features that have been registered with the
feature registry up to the point when this feature
is registered.
Implementation
Future<void> initialize(
FeatureConfig? config,
Map<String, Feature> registeredFeatures,
) async {}
