You get this error because in store=(phon.data['Name']);you try to set the value of the whole list as a string. Instead you should've set only the value of one of the lists fields as a string. For example store[0]=(phon.data['Name']);

List<String> store=[];
String name;
     void getData() async {
       await for(var snapshot in _firestore.collection('users').snapshots()){
         for(var phon in snapshot.documents){
         name=(phon.data['Name']);
         print(name);
       }
   } 
}

What you are doing is storing a String (phon.data['Name']) in a List. I have this sample code which has String named name and now storing Stringname in phon.data['Name']. you can also do the opposite.

Change store=(phon.data['Name']) to store.add(phon.data['Name']) You are trying to assign a single string (I assume that is what phon.data['Name'] is) to a List object.
