What amount of RAM will be allocated for storing an array of eight elements?

In Flutter (Dart), the amount of RAM allocated for an array of eight elements depends on the type of the elements. For example, if it is an array of 8 integers (int), each int takes 64 bits (8 bytes), so total 8 * 8 = 64 bytes.

If the array contains objects or strings, memory will be allocated for references to objects (usually 64-bit pointers), and the objects themselves are stored separately in the heap.

Example for an int array:

void main() {
  List<int> numbers = List.filled(8, 0);
  print(numbers.length); // 8
}

In total, for primitive types, the size equals the number of elements multiplied by the size of the type. For reference types, it includes memory for references plus memory for the objects.
