)

Creates a specification with the provided handlers.

If the handleUncaughtError is provided, the new zone will be a new "error zone" which will prevent errors from flowing into other error zones (see errorZone, sameErrorZone).

Implementation

const factory ZoneSpecification(
    {HandleUncaughtErrorHandler? handleUncaughtError,
    RunHandler? run,
    RunUnaryHandler? runUnary,
    RunBinaryHandler? runBinary,
    RegisterCallbackHandler? registerCallback,
    RegisterUnaryCallbackHandler? registerUnaryCallback,
    RegisterBinaryCallbackHandler? registerBinaryCallback,
    ErrorCallbackHandler? errorCallback,
    ScheduleMicrotaskHandler? scheduleMicrotask,
    CreateTimerHandler? createTimer,
    CreatePeriodicTimerHandler? createPeriodicTimer,
    PrintHandler? print,
    ForkHandler? fork}) = _ZoneSpecification;
