CacheConfig class

Configuration for the SDK's caching layer.

Controls TTLs, capacity limits, the default read policy, and offline queue retries.

Constructors

CacheConfig({int maxMessagesPerRoom = 500, int maxRooms = 100, Duration ttlMessages = const Duration(hours: 24), Duration ttlRooms = const Duration(hours: 12), Duration ttlUsers = const Duration(hours: 6), Duration ttlMembers = const Duration(hours: 12), CachePolicy defaultReadPolicy = CachePolicy.networkFirst, int offlineQueueMaxRetries = 5, int offlineQueueMaxAttachmentBytes = 10 * 1024 * 1024})

Properties

defaultReadPolicy → CachePolicy

final

hashCode → int

The hash code for this object.

no setter, inherited

maxMessagesPerRoom → int

final

maxRooms → int

final

offlineQueueMaxAttachmentBytes → int

Upper bound, in bytes, on a single attachment queued for offline retry (NomaChatClient.enqueueOfflineAttachment). An attachment upload that fails while over this size is NOT queued — queuing it would mean carrying its raw bytes through Hive on every persist of the offline queue, base64-encoded, indefinitely. Defaults to 10 MB, comfortably above a compressed photo/voice note but well under a raw video. The drop is reported via onOperationDropped (reason 'attachment_too_large') instead of failing silently.

final

offlineQueueMaxRetries → int

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

ttlMembers → Duration

Freshness window for a room's cached member roster (members:$roomId). Matches ttlRooms by default: a roster changes at the pace of the room, not of the message stream, and every local mutation plus every user_joined / user_left / user_role_changed event invalidates the key outright.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
