GateUiBuilder class final

GateUiBuilder — синхронный контроллер доступа с произвольной логикой.

Используется в случаях, когда стандартные гейты (PermissionGate, RoleGate, FeatureGate) не покрывают необходимые условия:

  • сложные выражения: user.isAdmin && region == 'KZ'
  • временные или контекстные условия
  • отладочные/экспериментальные фичи

⚠️ Не поддерживает асинхронные проверки!

Если вам нужно условие Future<bool>, используйте AccessGate<T>.


Пример:

GateUiBuilder(
  condition: (context) {
    final session = context.read<AuthSession>();
    return session.hasPermission('debug.view') && !session.isExpired;
  },
  builder: (context) => DebugPanel(),
)
