Flutter Dart LinkedHashSet Example

In dart LinkedHashSet works as a hash table including on a set implementation. LinkedHashSet is used where we want to keep track of the inserted data order.

Flutter Dart LinkedHashSet Example

1. Creating Empty LinkedHashSet.

 final tempName = <String>{};

2. Creating LinkedHashSet with default filled values.

final tempName = <String>{'A', 'B'};
 print(tempName);

3. Adding multiple values together in LinkedHashSet.

tempName.addAll({'C', 'D', 'E', 'F'});

4. Checking LinkedHashSet is Empty or Not.

print(tempName.isEmpty);

5. Get the length of LinkedHashSet.

print(tempName.length);

6. Find and check if certain value is present or not in LinkedHashSet.

  final b_Exists = tempName.contains('B');
  print(b_Exists);

7. Print all LinkedHashSet on Terminal screen one by one with For Each loop.

tempName.forEach(print);

8. Removing Single item from LinkedHashSet.

tempName.remove('E');

9. Creating a duplicate copy of LinkedHashSet.

 final copy = tempName.toSet();
  print(copy);

Source code for main.dart file:

void main() { 
  final tempName = <String>{'A', 'B'};
  print(tempName);
  tempName.addAll({'C', 'D', 'E', 'F'});
  print(tempName);
  print(tempName.isEmpty);
  print(tempName.length);
  final b_Exists = tempName.contains('B');
  print(b_Exists);
  tempName.forEach(print);
  tempName.remove('E');
  print(tempName);
  final copy = tempName.toSet();
  print(copy);
}
