Dart Classes

• Classes in Dart are used to define the structure and behaviour of objects.

• They consist of fields (variables) and methods (functions).

Dart Objects

• Objects are instances of classes. They represent specific instances of the blueprint defined by the class.

• You create objects using the new keyword followed by the class name and optional constructor arguments.

Reference Variable

• In Dart, variables that hold objects don't actually store the object directly instead, they hold references to where the object is stored in memory.

• When you create an object, Dart allocates memory for that object and returns a reference to it. This reference is what is stored in the variable.
