value property

@override T get value

The current value stored in this notifier.

When the value is replaced with something that is not equal to the old value as evaluated by the equality operator ==, this class notifies its listeners.

Implementation

@override
T get value => _value;

@override set value (T newValue)

Implementation

@override
set value(T newValue) {
  if (value != newValue) {
    _before = value;
  }
  super.value = newValue;
}
