List<E>.filled constructor
Creates a list of the given length with fill
at each position.
The length
must be a non-negative integer.
Example:
new List<int>.filled(3, 0, growable: true); // [0, 0, 0]
The created list is fixed-length if growable
is false (the default)
and growable if growable
is true.
If the list is growable, changing its length will not initialize new
entries with fill
.
After being created and filled, the list is no different from any other
growable or fixed-length list created using List.
All elements of the returned list share the same fill
value.
var shared = new List.filled(3, []);
shared[0].add(499);
print(shared); // => [[499], [499], [499]]
You can use List.generate to create a list with a new object at each position.
var unique = new List.generate(3, (_) => []);
unique[0].add(499);
print(unique); // => [[499], [], []]
Implementation
external factory List.filled(int length, E fill, {bool growable = false});
