ZenithAuthorizeView class

A declarative Flutter widget that shows different UI depending on whether a ZenithPolicy grants access.

Reactive: when a ZenithNode read inside policy.evaluate or policy.evaluateAsync changes value, the widget automatically rebuilds.

ZenithAuthorizeView(
  policy: exportPolicy,
  authorized: (ctx) => const ExportButton(),
  notAuthorized: (ctx, result) => const PaywallTrigger(),
  authorizing: (ctx) => const ShimmerPlaceholder(),
)

Constructors

ZenithAuthorizeView({Key? key, required ZenithPolicy policy, required Widget authorized(BuildContext context), required Widget notAuthorized(BuildContext context, AuthorizationResult result), Widget authorizing(BuildContext context)?, UserSecurityContext securityContext = const UserSecurityContext()})

Creates a ZenithAuthorizeView.

const

ZenithAuthorizeView.hidden({required ZenithPolicy policy, UserSecurityContext securityContext = const UserSecurityContext(), required Widget authorized(BuildContext context)})

A ZenithAuthorizeView that hides the authorized widget when denied (renders SizedBox.shrink instead of calling notAuthorized).

factory

ZenithAuthorizeView.locked({required ZenithPolicy policy, UserSecurityContext securityContext = const UserSecurityContext(), required Widget authorized(BuildContext context), Widget notAuthorized(BuildContext, AuthorizationResult)?})

A ZenithAuthorizeView that shows a locked icon/overlay when denied.
