fillRange method Null safety
Sets the objects in the range start
inclusive to end
exclusive
to the given fillValue
.
The provided range, given by start
and end
, must be valid.
A range from start
to end
is valid if 0 <= start <= end <= len
, where
len
is this list's length
. The range starts at start
and has length
end - start
. An empty range (with end == start
) is valid.
Example:
List<int> list = new List(3);
list.fillRange(0, 2, 1);
print(list); // [1, 1, null]
If the element type is not nullable, omitting fillValue
or passing null
as fillValue
will make the fillRange
fail.
Implementation
void fillRange(int start, int end, [E? fillValue]);
