Flutter firebase adding new data

Question

I have a button which is create a new data for firebase. But when i change the data its updating , but i want to add a new one. For example , this is my set part;

IconButton( onPressed: () { _firestore.collection("UsersTodos").doc(username).set({ 'userTodo': [_todoController.text], }); }, icon: Icon(Icons.add)),

When i enter another value to textfield my document is updating and change the value, i need to create an another value for that document.

Shall i loop this area with for loop ?

Try this code, it should add items to list:

 _firestore.collection("UsersTodos").doc(username).update({ 'userTodo': FieldValue.arrayUnion([_todoController.text]), });

It worked. Thanks a lot. But there is a problem. My data comes like [first,second,third] i want to seperate them. When i get them like listofDocumentSnap[index]['userTodo'] it is not coming 1 by 1 . Its comming like array i want to seperate them

I think this method won't work. I need to convert this like userTodo0 , userTodo1,userTodo2
