length property

@override int length

The number of objects in this list.

The valid indices for a list are 0 through length - 1.

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

Implementation

@override
int get length => _wrappedList.length;

@override void length=(int newLength)

Unsupported -- violated non-null constraint imposed by protobufs.

Changes the length of the list. If newLength is greater than the current length, entries are initialized to null. Throws an UnsupportedError if the list is not extendable.

Implementation

@override
set length(int newLength) => throw _unsupported('set length');
