# Variables

### Instructions

In Dart you can declare variables in two ways:

```dart
var strPatrick = 'Patrick';
// or ...
String strSpongebob = 'Spongebob';
```

- The first way declares using `var` which detects variable types automatically.
- The second way explicitly declares using variable's type, in the example it is `String`.

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);
- constant `pi` of type `double` containing pi value with 2 decimal points;
- Note: no main needed!
