How to Retrieve a list of top-level collection of Documents of this type? any one with a solution
我需要在数组中显示所有文档 ID 的内容
我在 Flutter 中使用 firebase;
这是我的职能:
getlist()async{
var snapshot = await _firestore.collection("posts").get();
var data = snapshot.docs.map((doc)=> doc.data());
return data;
}
I need to able to access top-level collection of this type any one with a solution
尝试使用“.toList()”
感谢大家的帮助support.but这就是我设法解决问题的方法。
CollectionReference _collectionRef = _firestore.collection("posts"); QuerySnapshot querySnapshot = await _collectionRef.get(); final allData = querySnapshot.docs.map((e) => e.data()).toList();
