length property Null safety

int length
override

The number of objects in this list.

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

Implementation

external int get length;
void length=(int length)
override

Changes the length of this list.

The list must be growable. If newLength is greater than current length, new entries are initialized to null, so newLength must not be greater than the current length if the element type E is non-nullable.

Implementation

external void set length(int length);
