Methods

cancel(ControlSubscription<T?> subscription) → void
override
cast<U>() → ObservableValue<U>
inherited
clear() → void
Clears all values in stack. Even if isRooted is set to true.
contains(T item) → bool
Checks if given item is in stack.
disableRoot() → void
Disables root value. So stack can pop all values.
dispose() → void
Used to clear and dispose object. After this method call is object typically unusable and ready for GC. Can be called multiple times!
override
Pops until last item in stack. Returns true if there is nothing to pop.
noSuchMethod(Invocation invocation) → dynamic

inherited
notify() → void
override
pop() → void
Pops last value from stack.
popTo(T value) → void
Pops to given value. All next values are removed from stack.
popToFirst() → void
Pops to root/first value of stack. All next values are removed from stack.
popToLast() → void
Pops to last value of stack. All previous values are removed from stack.
popUntil(Predicate<T?> test) → void
Pops to value of given test. All next values are removed from stack.
push(T? value) → void
Push given value to end of stack.
pushStack(Iterable<T?> stack, {bool clearOrigin = false}) → void
Pushes whole stack. Set clearOrigin to clear previous stack.
pushUnique(T value) → void
Push given value to end of stack. Previous occurrence of value is removed from stack.
setValue(T? value, {bool notify = true, bool forceNotify = false}) → void
override
subscribe(ValueCallback<T?> action, {bool current = true, dynamic args}) → ControlSubscription<T?>
override
toString() → String
A string representation of this object.

operator [](int index) → dynamic
