List of Class Objects operation in Dart - dart

Question

Have an issue in the below chunk of code.
class Events
{
// some member variables
}
class SVList
{
String name;
int contentLen;
List<Events> listEvents;
SVList()
{
this.name = "";
this.contentLen = 0;
this.listEvents = new List<Events>();
}
}
class GList
{
List<SVList> listSVList;
GList(int Num)
{
this.listSVList = new List<SvList>(num);
}
}
function f1 ()
{
//array of class objects
GList gList = new GList(num);
}
Not able to find "listEvents" member after GList constructor is called. Am I missing anything here.
Referencing glist.listSVList[index] --> do not find member variable 'listEvents'. Any pointers appreciated.
To elaborate , no member variable with 'glist.listSVList[index].listEvents' is found.

Answer 1

you have a typo here:
this.listSVList = new List<SvList>(num); // <== SVList not SvList
function seems wrong here
function f1 () { ... }
in this case you use function as a return type
another typo:
GList(int Num) // <== Num (uppercase)
{
this.listSVList = new List<SvList>(num); // <== num (lowercase)
}
this code worked:
class Events {
// some member variables
}
class SVList {
String name;
int contentLen;
List<Events> listEvents;
SVList() {
this.name = "";
this.contentLen = 0;
this.listEvents = new List<Events>();
}
}
class GList {
List<SVList> listSVList;
GList(int num) {
this.listSVList = new List<SVList>(num);
}
}
main() {
//array of class objects
GList gList = new GList(5);
gList.listSVList[0] = new SVList();
gList.listSVList[0].listEvents.add(new Events());
print(gList.listSVList[0].listEvents.length);
}
What editor are you using?
DartEditor showed all errors immediately after I pasted your code.

Lists in Dart can now be stated as
List<Object> array = []
