### Instructions
You can declare variables in two ways. The type can be implicitly detected using the `var` keyword, or explicitly by declaring the variable's type:
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:
```dart
var strPatrick = 'Patrick';

String strSpongebob = 'Spongebob';
```
Declare and initialize the following variables:
- 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.
- `obj` of type `Object`, containing any value.
- `planet` of type `String`, containing the name of the planet you live on.
- `year` of type `int`, containing the current year.
- `lucky` of type `bool`, containing `true` or `false` (you decide).
- constant `pi` of type `double`, containing pi value with 2 decimal places
