removeDuplicates(){
final list = [1, 2, 2, 3, 4, 4, 4];
return list.toSet().toList();
}
Output: [1,2,3,4]
Explanations: First we initialized a variable called list to an array that contains some duplicates, then we converted it to a set(as sets can not contain duplicates) and then back to a list.

simpler
final list = [1, 2, 2, 3, 4, 4, 4].toSet().toList();
Yes but for an example doing things step by step is better, for readability.
.toList()); ?
Changed thanks 😊
