List<E>.generate constructor

List<E>.generate(

1. int length,
2. E generator(
   1. int index
   ),
3. {bool growable = true}

)

Generates a list of values.

Creates a list with length positions and fills it with values created by calling generator for each index in the range 0 .. length - 1 in increasing order.

List<int>.generate(3, (int index) => index * index); // [0, 1, 4]

The created list is fixed-length if growable is set to false.

The length must be non-negative.

Implementation

external factory List.generate(int length, E generator(int index),
    {bool growable = true});
