i just want to filter the queries when conditions true query " norequest >= 5 " it should get the those query or doc's " coordinates " and add the results to a list. How can i do that?

CodePudding user response：

1. You need to declare norequest field to Integer.

2. Than you got a List<Map<String, dynamic>> where you can set many filter

Code example:

QuerySnapshot query = await firestore
    .collection('stations')
    .where('norequest', isGreaterThanOrEqualTo: 5)
    .get();
