I have already make a listview where the data is displayed but I can't do something with that, for example, add it to a list or something. Thanks

推荐答案

您可以通过获取以下文档列表来做到这一点:

You can do that by getting list of documents like:

final QuerySnapshot result =
          await Firestore.instance.collection('myCollection').getDocuments();
final List<DocumentSnapshot> documents = result.documents;

然后您可以遍历此列表并获取数据:

And after that you can iterate this list and get data:

documents.forEach((data) => print(data));
