Implemented types

Constructors

OffsetIteratorController({String name = 'OffsetIteratorController', bool closeOnError = true, OffsetIteratorControllerTransform<T>? transform, SeedCallback<T>? seed, int retention = 0})

Properties

closeOnError → bool
If true, when addError is called, the controller will be closed.

latefinal
runtimeType → Type
A representation of the runtime type of the object.

no setter
state → OffsetIteratorControllerState
The internal state of the controller.
