clear method Null safety

  1. @override
void clear()
override

Removes all objects from this list; the length of the list becomes zero.

The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.clear();
print(numbers.length); // 0
print(numbers); // []

Implementation

@override
void clear() {
  throw UnsupportedError('Cannot clear a fixed-length list');
}
