//Here I am trying to add document on firestore with users uid but could not get any solution
                  final uid = await Provider.of(context).auth.getCurrentUID();
                 Map <String, dynamic> data = {"field1": sampledata1.text, "field2": sampledata2.text};
                  //FirebaseFirestore.instance.collection("UserData").add(data);
                },

推荐答案

调用 add(...)时，Firestore会自动为您生成新文档的ID.

When you call add(...) Firestore auto-generates an ID for the new document for you.

如果要自己控制ID，请使用 doc(uid).set(...):

If you want to control the ID yourself, use doc(uid).set(...):

FirebaseFirestore.instance.collection("UserData").doc(uid).set(data);
