ValueChanged<T> class

Represents a change in a single observable value.

This event is typically dispatched when a reactive value updates from an old value to a new value. It holds both values so that you can compare or react accordingly.

Example

void main() {
  // Suppose you are observing a value
  var oldValue = 10;
  var newValue = 20;

  var event = ValueChanged<int>(oldValue, newValue);

  print(event.oldValue); // 10
  print(event.newValue); // 20
}
