Sure! In Dart, you can sort an array using the sort() method that is available for the List class. This method sorts the array in ascending order by default. Here is an example:
void main() {
List numbers = [4, 1, 5, 2, 3];
numbers.sort();
print(numbers); // Output: [1, 2, 3, 4, 5]
}
As you can see, we've created an array of integers called numbers. We then called the sort() method on the numbers array, which sorted the array in ascending order. Finally, we printed the sorted array using print().
If you want to sort the array in descending order, you can use the sort() method in conjunction with the compareTo() method. Here is an example:
void main() {
List numbers = [4, 1, 5, 2, 3];
numbers.sort((a, b) => b.compareTo(a));
print(numbers); // Output: [5, 4, 3, 2, 1]
}
In this example, we've passed a function as a parameter to the sort() method. This function compares two values a and b, and returns -1, 0, or 1 depending on whether a is less than, equal to, or greater than b, respectively. By reversing the order of the values being compared (with b.compareTo(a)) we can sort the array in descending order.
