List != List<int> != List<String> != List<dynamic> How do i make sure if type == list returns true in dart

listType(example) {
  var x = example.runtimeType;
  if (x == List) { 
    return true;
  } else {
    return false;
  }
}

print(listType([1, 2, 3, 4]));

You can swap swap x==List with x==List< int> and see the difference!!!

How do i make it so that runtimeType always returns true as long as the return type is a list?

>Solution :

If you want to check the type use is and do not use runtimeType because it make x a type not list<int>, like this:

listType(example) {
  
  if (example is List) { //<--- here
    return true;
  } else {
    return false;
  }
}
