ParameterOptional/RequiredDescription

✐ Example

1 Equality check for Future objects with same values

In this example,

  1. We create two Future objects future1 and future2, both containing the value 42.
  2. We use the equality operator == to check if future1 is equal to future2.
  3. We then print the result of the equality check to standard output.

Dart Program

void main() {
  Future<int> future1 = Future<int>.value(42);
  Future<int> future2 = Future<int>.value(42);
  bool areEqual = (future1 == future2);
  print('Are future1 and future2 equal? $areEqual');
}

Output

Are future1 and future2 equal? false
