How can I get data from firebase cloud?-CodePudding

I have a collection of data linked like this

users => doc(Current user) => last_msg => doc => some data

I am not getting the data, I received null every time.

  _fireStore
        .collection('users')
        .doc(currentUserId)
        .collection("lase_msg")
        .doc("cHxIpGAoxhkRZYo9EjgX")
        .get()
        .then((DocumentSnapshot documentSnapshot) {
      userlstMsg = documentSnapshot.data() as Map<String, dynamic>;
    });

this is my code and i am receiving null but i should have this data

cHxIpGAoxhkRZYo9EjgX_msg
"fffffffff"
cHxIpGAoxhkRZYo9EjgX_time

CodePudding user response：

You are having a typo lase_msg will be last_msg

_fireStore
        .collection('users')
        .doc(currentUserId)
        .collection("last_msg") //here
        .doc("cHxIpGAoxhkRZYo9EjgX")
        .get()
