<itemvalue="Called when this object is removed from the tree permanently. The framework calls this method when this [State] object will never build again. After the framework calls [dispose], the [State] object is considered unmounted and the [mounted] property is false. It is an error to call [setState] at this point. This stage of the lifecycle is terminal: there is no way to remount a [State] object that has been disposed. Subclasses should override this method to release any resources retained by this object (e.g., stop any active animations). {@macro flutter.widgets.State.initState} Implementations of this method should end with a call to the inherited method, as in `super.dispose()`. See also: [deactivate], which is called prior to [dispose]."/>

<itemvalue="Reduces a collection to a single value by iteratively combining elements of the collection using the provided function. The iterable must have at least one element. If it has only one element, that element is returned. Otherwise this method starts with the first element from the iterator, and then combines it with the remaining elements in iteration order, as if by: ``` E value = iterable.first; iterable.skip(1).forEach((element) { value = combine(value, element); }); return value; ``` Example of calculating the sum of an iterable: ```dart final numbers = <double>[10, 2, 5, 0.5]; final result = numbers.reduce((value, element) => value + element); print(result); 17.5"/>
