Remember that .map returns Iterable<T>.
Whenever you need a list you have to cast iterable to the list by adding .toList():
_clanoviZaDijeljenje.map((member) { return Text(member.name);}).toList();

So should add members to the list with map, and then to display names iterate thorugh that list?
Chris
var members = _clanoviZaDijeljenje.map((member) { return Text(member.name);}).toList(); then display the list: Column(children: members) You can omit assigning members variable and directly assign children.You can use foreach cycle.
First way:
_clanoviZaDijeljenje.forEach((member) return Text(member.name));
Second way:
for(Member member in _clanoviZaDijeljenje){ return Text(member.name);}
