How to Split a List in Dart ?

Answer

To split a list in Dart, you can use the sublist method or iterate through the list manually to create sublists.

✐ Examples

1 Split a List Using sublist

In this example,

We create a list named numbers with initial integer values.
We use the sublist method to create a sublist from the original list, specifying the start and end indices.
The sublist method returns a new list containing the specified range of elements from the original list.
Finally, we print the sublist to standard output.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3, 4, 5, 6, 7, 8];
  int chunkSize = 3;
  for (int i = 0; i < numbers.length; i += chunkSize) {
    List<int> chunk = numbers.sublist(i, i + chunkSize < numbers.length ? i + chunkSize : numbers.length);
    print('Chunk: $chunk');
  }
}

Output

Chunk: [1, 2, 3]
Chunk: [4, 5, 6]
Chunk: [7, 8]

2 Split a List Manually

In this example,

We create a list named numbers with initial integer values.
We define a chunk size.
We use a for loop to iterate over the list and create sublists of the specified chunk size.
The sublists are stored in a list, where each element represents a chunk of the original list.
Finally, we print the list of chunks to standard output.

Dart Program

void main() {
  List<int> numbers = [1, 2, 3, 4, 5, 6, 7, 8];
  int chunkSize = 3;
  List<List<int>> chunks = [];
  for (int i = 0; i < numbers.length; i += chunkSize) {
    chunks.add(numbers.sublist(i, i + chunkSize < numbers.length ? i + chunkSize : numbers.length));
  }
  for (List<int> chunk in chunks) {
    print('Chunk: $chunk');
  }
}

Output

Chunk: [1, 2, 3]
Chunk: [4, 5, 6]
Chunk: [7, 8]
