List with explicit mixed types in Dart

Is there a way of defining a List in Dart with mixed types, while explicitly setting the types of each element?

I know there is a Tuple type that does this, but I was hoping there is a way of doing it with the built-in List type.

(Right now my way of doing so is using a List<dynamic> or a List<Object>)

Example of what I'm looking for:

final mixedList = <bool, String>[false, 'Hello'];

No.

That thing is a tuple, not a list (sequence of similarly typed values).

If you could create a <bool, String>[false, 'Hello'] list, then the type of list[0] and list[1] depends on the value of the index. That breaks static typing, since it's a kind of dependent typing (the type of an expression depends on the value of another).
