如何手动将文档字段添加到本地 QueryDocumentSnapshot 列表

Question

i have the following list

List <QueryDocumentSnapshot>  globalVideosUrls = [] ;

for example if we use the following

 FirebaseFirestore.instance.collection('users')
            .limit(1).get().then((value){
             globalVideosUrls.add(value)
        });

it will add as expected

but what if i want to manually add the following data into globalVideosUrls

document id

00dcb026-3163-4ca0-859e

fields

 'videoType':'peace'

 'url':'url'


.

globalVideosUrls .add(????)

You have to replace the type "QueryDocumentSnapshot" with QuerySnapshot and then you will get multiple docs and with there data also try this If any questions then ask. thanks.

List<QuerySnapshot> globalVideosUrls = [];
List<String> videoUrlList = [];
await FirebaseFirestore.instance
    .collection('users')
    .get()
    .then((value) {
  globalVideosUrls.add(value);
});
globalVideosUrls.forEach((element) {
  element.docs.forEach((docELe) {
    print("data:- ${docELe.data()}");
    Map map = docELe.data() as Map;
    videoUrlList.add(map['url']);
  });
});
