I have a ListView which is displaying documents from a Firebase Query... but I can't seem to figure out how to get it to Randomize (shuffle) the results each time.
Randomize / Shuffle ListView displaying Firebase Documents from filtered Query
Actions & Logic
Resolved
Tried following this thread this from Serge Middendorf which works for shuffling lists, but the query does not send back a list (at-least that's accessible), it sends back documents.
Serge confirmed his action requires a list... but only individual documents are an option here.
I also explored copying the code from the ListView widget to make a custom widget with adding shuffle to it. But figuring out all the parameters and dependencies etc to get it to work/pass the code check (it just gets stuck) is beyond my FF knowledge.\
This seems to be the main bit of the code... 'reverse: true,' lives in there... 🤷♂️
List<TaskRecord> listViewTaskRecordList = snapshot.data!;
return ListView.separated(
padding: EdgeInsets.symmetric(vertical: 10.0),
reverse: true,
shrinkWrap: true,
scrollDirection: Axis.vertical,
itemCount: listViewTaskRecordList.length,
separatorBuilder: (_, __) => SizedBox(height: 10.0),
itemBuilder: (context, listViewIndex) {
final listViewTaskRecord = listViewTaskRecordList[listViewIndex];
Is there any way to add a step in between that would modify the widget code, or intercept the list it gets back from the query to re-order it?
Yes
