insert method

  1. @override
void insert(
  1. int index,
  2. E element
)
override

Inserts the object at position index in this list.

This increases the length of the list by one and shifts all objects at or after the index towards the end of the list.

The index value must be non-negative and no greater than length.

Implementation

@override
void insert(int index, E element) {
  assert(!isDisposed);
  _list.insert(index, element);
  _dirty = true;
  if (emitDetailedChanges)
    _changes.add(ListModification.insert(index, element));
}
