AccessContext<R, P, F> class abstract interface

AccessContext — a generic interface for access evaluation.

This interface abstracts permission, role, and feature flag checks away from the Flutter BuildContext, enabling usage in DI layers, BLoC, Riverpod, or anywhere outside the widget tree.

Type parameters:

  • R — Role type (e.g., String, enum Role)
  • P — Permission type (e.g., String, enum Permission)
  • F — Feature flag type (e.g., String, enum FeatureFlag)

Example:

final class SessionContext implements AccessContext<Role, Permission, FeatureFlag> {
  ...
}
