Abstract class Dart

In Dart, an object of a class can be created using new keyword followed by the class name . Below is general syntax to declare an object of a class. var objectName = new ClassName(<constructor_arguments>); Here, objectName and ClassName is replaced with actual object name and the class name respectively.

In order to make a variable or function private to a class, the name of the variable or function needs to start with underscore( _ ) . Variables/function without underscore( _ ) are public. You have defined a private function and accessing the private function.
