Size in Dart

In Dart, the length property can be used to get the size of an array. Here's an example:

void main() {
  List nums = [1, 2, 3, 4, 5];
  print(nums.length); // outputs 5
}

In the example above, we have an integer array nums with 5 elements. We get the size of the array using the length property and print it to the console.

You can also use the isEmpty property to check if an array is empty:

void main() {
  List fruits = [];
  print(fruits.isEmpty); // outputs true
}

In this example, we have an empty string array fruits. We use the isEmpty property to check if the array is empty and print the result to the console. The output would be true, indicating that the array is indeed empty.
