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>
, используйтеAccessGate<T>
.
Пример:
GateUiBuilder(
condition: (context) {
final session = context.read<AuthSession>();
return session.hasPermission('debug.view') && !session.isExpired;
},
builder: (context) => DebugPanel(),
)
