operator []= method
Sets the value at the given index
in the list to value
.
The index
must be a valid index of this list,
which means that index
must be non-negative and
less than length.
Implementation
@override
void operator []=(int index, E value) {
var oldValue = _list[index];
if (hasListObservers && oldValue != value) {
_notifyListChange(index, addedCount: 1, removed: [oldValue]);
}
_list[index] = value;
}
