如何在每次构建Query（）时禁用graphql_flutter查询后端

Question

I got a PageView in the home page with Query for a list of data, and every time push to another route will causing build . And the Query in build will call backend Api and rerender. How to avoid the query?

• build method cannot be disabled and make the Query widget init in initState won't work
• I found the issue should be in here: https://github.com/zino-app/graphql-flutter/blob/master/packages/graphql_flutter/lib/src/widgets/query.dart#L41 don't know why, any suggestions?

@override
Widget build(BuildContext context) {
  return Query(
    options: QueryOptions(
      document: queryDocument,
    ),
    builder: (QueryResult result, {VoidCallback refetch, FetchMore fetchMore}) {
      print('will call backend each push and pop route and the build causing by state changes');
    }
  );
}

Expect the builder won't be alway call and to reduce the backend query. (I'm new to graphql_flutter and the document is not cover such case.)
