How to create a Three Dimensional List in Dart ?

Answer

To create a three-dimensional list in Dart, you can use nested List structures to represent the multi-dimensional data.

✐ Examples

1 Create and Populate a 3D List

In this example,

We create a List>> structure to represent the three-dimensional list.
We use nested loops to populate the 3D list with integer values.
We print the elements of the 3D list to demonstrate the structure.

Dart Program

void main() {
  List<List<List<int>>> threeDList = [];

  for (int i = 0; i < 3; i++) {
    List<List<int>> plane = [];
    for (int j = 0; j < 2; j++) {
      List<int> row = [];
      for (int k = 0; k < 2; k++) {
        row.add(i * 4 + j * 2 + k + 1);
      }
      plane.add(row);
    }
    threeDList.add(plane);
  }

  for (var plane in threeDList) {
    for (var row in plane) {
      print(row);
    }
    print('');
  }
}

Output

[1, 2]
[3, 4]

[5, 6]
[7, 8]

[9, 10]
[11, 12]
