How to convert firebase map objects to a local list in flutter-CodePudding

I am trying to cache a firebase document filed to a local List. But I don't know how to do that.

Here is firebase document field I want to cache

This is the list I want:

List theListIwant = [
      {'aed': true},
      {'bet': false},
      {'med': true},
      {'zed': true},
    ];

DocumentSnapshot:

FirebaseFirestore.instance.collection('stores').doc(storeData.user.uid).snapshots()

I am stuck here:

List medicineList = (snapshot.data!
                            .get('meds') as Map)
                            .entries
                            .map((e) => null)

CodePudding user response：

First create a map from Firebase

and then

map convert to list

CodePudding user response：

your DocumentSnapshot

FirebaseFirestore.instance.collection('stores').doc(storeData.user.uid).collection('meds').snapshots()

Map dataa

snapshot.data!.docs.map((DocumentSnapshot document) {
                    Map<String, dynamic> data =
                        document.data()! as Map<String, dynamic>;
                    List theListIwant = [
                       {'aed': data["aed"]},
                       {'bet': data["bet"]},
                       {'med': data["med"]},
                       {'zed': data["zed"]},
                    ];
                  }
