reshape method
Reshaping means changing the shape of an array.
var reshape = m2d.reshape([ [0, 1, 2, 3, 4, 5, 6, 7]],2,4);
print(reshape);
//[[0, 1, 2, 3], [4, 5, 6, 7]]
Implementation
List reshape(List list, int row, int column) {
var listShape = shape(list);
if (listShape[0] != 1 || listShape[0] == 1) list = flatten(list);
var copy = list.sublist(0);
list.clear();
for (var i = 0; i < copy.length; i++) {
var r = i ~/ column;
if (list.length <= r) list.add([]);
list[r].add(copy[i]);
}
return list;
}
