How to create a new List out of two Lists

example.dart

void main() {
  List<DensityVolume> listDensity = [DensityVolume(2.3, 3.2), DensityVolume(4.2, 2.4)];
  List<HeightLengthWidth> listHeight = [HeightLengthWidth(1, 1, 1), HeightLengthWidth(2, 2, 2)];

  List<Cube> result = [];

  for (var i = 0; i < listDensity.length; i++) {
    final densityElement = listDensity[i];
    final heightElement = listHeight[i];
    result.add(Cube(
      densityElement.density,
      densityElement.volume,
      heightElement.length,
      heightElement.height,
      heightElement.width,
    ));
  }
  print(result);
}

class Cube {
  final double density;
  final double volume;
  final int length;
  final int height;
  final int width;

  Cube(this.density, this.volume, this.length, this.height, this.width);
}

class DensityVolume {
  final double density;
  final double volume;

  DensityVolume(this.density, this.volume);
}

class HeightLengthWidth {
  final int length;
  final int height;
  final int width;

  HeightLengthWidth(this.length, this.height, this.width);
}
