# length property

int length

Returns the number of objects in this list.

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

## Implementation

    int get length;

void length= (int newLength)

Changes the length of this list.

If `newLength` is greater than the current length, entries are initialized to `null`.

Throws an UnsupportedError if the list is fixed-length.

## Implementation

    set length(int newLength);
