concat<T> function

List<T> concat<T>(List<T> array, List values)

Concatenates a given list array with one or more dynamic values.

The array parameter is the original list of type List<T> to which the values will be concatenated. The values parameter is a list of dynamic values to concatenate to the array.

If any of the values in values are also lists of type List<T>, their elements will be added individually to the result. Otherwise, the value itself will be added to the result list.

Returns a new list of type List<T> containing the elements of the original list array and the concatenated dynamic values.

Example:

var originalList = [1, 2, 3];
var valuesToAdd = [4, [5, 6], 7];
var concatenatedList = concat<int>(originalList, valuesToAdd);
print(concatenatedList); // Output: [1, 2, 3, 4, 5, 6, 7]

Implementation

List<T> concat<T>(List<T> array, List<dynamic> values) {
  List<T> result = List<T>.from(array); // Copy the original array

  for (var value in values) {
    if (value is List<T>) {
      result.addAll(
          value); // If the value is a list, add its elements individually
    } else {
      result.add(value); // Otherwise, add the value itself
    }
  }

  return result;
