onQueryChange property

(void Function(List<Map>? next, {List<Map>? prev})?) onQueryChange

It is a callback function which accepts widget's nextQuery and prevQuery as parameters.

It is called everytime the widget's query changes. This property is handy in cases where you want to generate a side-effect whenever the widget's query would change.

Implementation

final void Function(List<Map>? next, {List<Map>? prev})? onQueryChange;
