<itemvalue="Creates a new repeating timer. The [callback] is invoked repeatedly with [duration] intervals until canceled with the [cancel] function. The exact timing depends on the underlying timer implementation. No more than `n` callbacks will be made in `duration n` time, but the time between two consecutive callbacks can be shorter and longer than `duration`. In particular, an implementation may schedule the next callback, e.g., a `duration` after either when the previous callback ended, when the previous callback started, or when the previous callback was scheduled for - even if the actual callback was delayed."/>
<itemvalue="The [ValueListenable] whose value you depend on in order to build. This widget does not ensure that the [ValueListenable]'s value is not null, therefore your [builder] may need to handle null values."/>
<itemvalue="A [ValueWidgetBuilder] which builds a widget depending on the [valueListenable]'s value. Can incorporate a [valueListenable] value-independent widget subtree from the [child] parameter into the returned widget tree."/>
<itemvalue="A [valueListenable]-independent widget which is passed back to the [builder]. This argument is optional and can be null if the entire widget subtree the [builder] builds depends on the value of the [valueListenable]. For example, in the case where the [valueListenable] is a [String] and the [builder] returns a [Text] widget with the current [String] value, there would be no useful [child]."/>
