What is Variable?
A Dart variable is a piece of memory that can contain
a data value.

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.

Unlike Java, Dart doesn’t have the keywords
public, protected, and private.
We can use (_) for making variable private.

Identifiers can not start with numbers.
Identifiers can start with a letter or
underscore (_), followed by any combination of
those characters plus digits.

Dart Supports Null safety
Null safety was introduced in Dart 2.12
