A value of type 'List<int>' can't be assigned to a variable of type 'Iterable<int>'

Question

I don't know if this was happening before my switch to the beta channel in Flutter but I don't understand why this is an error. A List is an Iterable right? I took the example from the official docs.

Iterable<int> example() {
  Iterable<int> iterable = [1, 2, 3];
  return iterable;
}

VSCode marks the list with a red underline telling me:

A value of type 'List<int>' can't be assigned to a variable of type 'Iterable<int>'.
Try changing the type of the variable, or casting the right-hand type to 'Iterable<int>'. dart(invalid_assignment)

Answer 1

You need convert again the results to List adding .toList() in the end because Dart changes the type of the variable.
