List<E>.generate constructor
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.
new List<int>.generate(3, (int index) => index * index); // [0, 1, 4]
The created list is fixed-length unless growable
is true.
Implementation
factory List.generate(int length, E generator(int index),
{bool growable: true}) {
List<E> result;
if (growable) {
result = <E>[]..length = length;
} else {
result = new List<E>(length);
}
for (int i = 0; i < length; i++) {
result[i] = generator(i);
}
return result;
}
