toList method

1. bool growable = true,

Creates a List containing the elements of this Iterable.

The elements are in iteration order. The list is fixed-length if growable is false.

Example:

final planets = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Mars'};
final keysList = planets.keys.toList(growable: false); // [1, 2, 3]
final valuesList =
 planets.values.toList(growable: false); // [Mercury, Venus, Mars]

Implementation

List<E> toList({bool growable = true}) {
 if (this.isEmpty) return List<E>.empty(growable: growable);
 var first = this[0];
 var result = List<E>.filled(this.length, first, growable: growable);
 for (int i = 1; i < this.length; i++) {
 result[i] = this[i];
 }
 return result;
}
