Future<List<dynamic>> _dataFetcher(int index, int limit,
[String searchTerm]) async {
await Future.delayed(Duration(milliseconds: 1000));
List list = [];
if (index == 60) {
// returning empty List tells to the FetchMoreBuilder data finished.
return list;
}
for (int i = 0; i < limit; i++) {
Random rdm = Random();
list.add(rdm.nextInt(100));
}
return list;
}
