Variables

Instructions

Declare and initialize following variables:

• obj of type Object containing any value;
• planet of type String containing planet's name you live on;
• year of type int containing current year;
• lucky of type bool containing true of false (you decide);
• pi which is a constant of type double containing the value of pi with 2 decimal points;

Hints

There are two ways to declare variables in Dart:

var strPatrick = 'Patrick';

String strSpongebob = 'Spongebob';

• The first way declares using var which detects variable types automatically.
• The second way explicitly declares the variable's type using the appropriate keyword, such as String for strings, as shown in the example.

Note: main is not needed!
