How to create a Two Dimensional List in Dart ?

Answer

To create a Two-Dimensional List in Dart, you can use nested lists or lists of lists to represent rows and columns.

✐ Examples

1 Create a 2D List of Integers

In this example,

We define a 2D list variable using List> with integers as the data type.
We initialize the elements of the 2D list with integer values.
We print the 2D list to the console.

Dart Program

void main() {
  List<List<int>> matrix = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9],
  ];

  matrix.forEach((row) {
    print(row);
  });
}

Output

[1, 2, 3]
[4, 5, 6]
[7, 8, 9]

2 Create a 2D List of Strings

In this example,

We define a 2D list variable using List> with strings as the data type.
We initialize the elements of the 2D list with string values.
We print the 2D list to the console.

Dart Program

void main() {
  List<List<String>> matrix = [
    ['apple', 'banana', 'cherry'],
    ['orange', 'grape', 'kiwi'],
  ];

  matrix.forEach((row) {
    print(row);
  });
}

Output

[apple, banana, cherry]
[orange, grape, kiwi]
