Select find all in Dart

In Dart, you can find all elements of an array satisfying a condition by using the where method, which allows you to filter the array based on a given condition.

Here's an example:

void main() {
  // create an array of integers
  List numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
  
  // find all even numbers using where method
  List evenNumbers = numbers.where((number) => number % 2 == 0).toList();
// print the even numbers

  print(evenNumbers); // [2, 4, 6, 8, 10]

}

In this example, we have an array of integers numbers. We use the where method to filter out only the even numbers. The where method takes a function that is called for each element in the array. If the function returns true, the element is included in the resulting array. In our example, the function (number) => number % 2 == 0 returns true if the number is even. We call toList() method on the resulting iterable to convert it back to a List. Finally, we print out the resulting array of even numbers.

You can apply this approach to any type of array and any condition that you need to check.
