DO NOT use this class directly - it's for internal use only.

DartWorkerInternal({required String callbackId, required int callbackHandle, Map<String, dynamic>? input, bool autoDispose = false, int? timeoutMs, String? onStoppedId, int? onStoppedHandle, int? cancelGraceMs}): const

autoDispose → bool: Whether to dispose Flutter Engine immediately after task completes.
final
callbackHandle → int: Serializable callback handle for cross-isolate communication.
final
callbackId → String: ID of the registered callback.
final
cancelGraceMs → int?: Grace budget in milliseconds. null means notify-only — never tear the engine down. See DartWorker.cancelGrace.
final
hashCode → int: The hash code for this object.
no setterinherited
input → Map<String, dynamic>?: Optional input data (will be JSON encoded).
final
onStoppedHandle → int?: Serializable handle of the stop handler, for the headless-isolate path (issue #75). The background isolate never runs initialize(), so it has no registry to look onStoppedId up in and must resolve by handle.
final
onStoppedId → String?: ID of the registered stop handler, for the main-isolate path (issue #75).
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
timeoutMs → int?: Maximum time in milliseconds the callback is allowed to run. null means use the platform default (5 min).
final
workerClassName → String: Get the worker class name for native side.
no setteroverride

noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toMap() → Map<String, dynamic>: Convert to map for platform channel.
override
toString() → String: A string representation of this object.
