Properties

changes Stream<ListChange<E>>
The stream of Changes to notify your UI or other state elements that they should update.
read-only, inherited
emitDetailedChanges bool
Whether to emit changes that include detailed information about the specific change. Defaults to false which will emit the same cached change object to minimize garbage collection. [...]
final, inherited
first ↔ E
Returns the first element. [...]
read / write, inherited
hashCode int
The hash code for this object. [...]
read-only, inherited
isDisposed bool
Whether this has been disposed.
read-only, inherited
isEmpty bool
Returns true if there are no elements in this collection. [...]
read-only, inherited
isNotEmpty bool
Returns true if there is at least one element in this collection. [...]
read-only, inherited
iterator Iterator<E>
Returns a new Iterator that allows iterating the elements of this Iterable. [...]
read-only, inherited
last ↔ E
Returns the last element. [...]
read / write, inherited
length int
The number of objects in this list. [...]

parent ChangeEmitter<Change>
read-only, inherited
reversed Iterable<E>
An Iterable of the objects in this list in reverse order.
read-only, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
single → E
Checks that this iterable has only one element, and returns that element. [...]
