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, T value) {
_context.conditionallyRunInAction(() {
final oldValue = _list[index];
if (oldValue != value) {
_list[index] = value;
_notifyElementUpdate(index, value, oldValue);
}
}, _atom);
}
