How acces to the values of a Set

Question

I'am a begginer in Dart and i dont know how to acces to the values of the next Set

Set mySet = Set.from(['Please', 'Help', 'Me']);

I didn't get the clarity of what you mean by accessing next set but, you can access your current set data in following ways.

Set mySet = Set.from(['Please', 'Help', 'Me']); // declaration.

Accessing through index

print('mySet.elementAt(0): ${mySet.elementAt(0)}');
print('mySet.elementAt(1): ${mySet.elementAt(1)}');
print('mySet.elementAt(2): ${mySet.elementAt(2)}');

Iterating over set.

mySet.forEach((value) => {print(value)});

Logging to see data stored in current set.

print('mySet: ${mySet.toString()}');

Solution 2

From Wikipedia:

Unlike most other collection types, rather than retrieving a specific element from a set, one typically tests a value for membership in a set.

That is, if this is not possible (to acces to the values) then this does not mean that this data structure does not fulfill its purpose.
Maybe you should choose a different, and at the same time, more suitable, for your purposes, data structure?
