Flutter List Map String Dynamic

Map dynamic to list flutter dynamic map dart flutter use map string dynamic how to map dynamic object flutter firebase snapshot the type 'stream' used in the 'for' loop must implement iterable. But now i'm frustrated because i want to make an infinite load and don't get it to work. A map is an object that associates keys and values.

The problem is your frommap constructor is reading from a map<<strong>string</strong>, dynamic>, so i bet that all of the lists in that map are actually list<<strong>dynamic</strong>> or just dynamic. However, both keys and values can be any type of object. Item class is more clear for the keys and the types of the values.

Map with string keys list map and list can in turn contain objects of any of the primitive classes, for example other map, list, etc (and even the parametric type can actually be different from dynamic).

To convert each element in the map to a string, tostring () is used. Map<string, dynamic> maps a string key with the dynamic value. List is not a subtype of type map this means the data which you are receiving after hitting a web service is in form of a list but inside the data class which you have used is of type map. List<<strong>map</strong><<strong>string</strong>, dynamic>> in flutter code example.
