BulkChange constructor

Represents multiple observable events grouped together.

This event is useful for batching changes, so instead of emitting multiple ValueChanged, ListChange, or MapChange events individually, you can group them into a single BulkChange.

Example

void main() {
  var events = [
    ValueChanged<int>(1, 2),
    ListChange.add(0, 'apple'),
    MapChange.put('key', null, 'value'),
  ];

  var bulk = BulkChange(events);

  print(bulk.changes.length); // 3
}
