42. C Important Concepts
• Everything you can place in a variable is an object, and every
object is an instance of a class. Even numbers, functions, and null
are objects.
• Although Dart is strongly typed, type annotations are optional
because Dart can infer types.
• Dart supports generic types, like List<int> (a list of integers) or
List<Object> (a list of objects of any type).
• Dart supports top-level functions (such as main()),
• Similarly, Dart supports top-level variables, as well as variables
tied to a class or object (static and instance variables). Instance
variables are sometimes known as fields or properties.
• Dart doesn’t have the keywords public, protected, and private. If an
identifier starts with an underscore (_), it’s private to its library. 16
