 Here's an example of creating a variable and assigning a value to it:
 
 {% highlight dart %}
 var name = 'Bob';
 {% endhighlight %}
 
 Variables are references. The variable named `name` contains a reference
 to a String object with a value of "Bob".

 You have the option of adding static types to your variable declarations:
 
 {% highlight dart %}
 String name = 'Bob';
 {% endhighlight %}
 
 Adding types is a way to clearly express your intent.
 Tools like compilers and editors can use these types to
 help you, by providing early warnings for bugs and code completion.

 #### final
 
 If you never intend to change a variable, use `final` instead of var or in
 addition to a type. Once a `final` variable is set, it can't be changed.
 
 {% highlight dart %}
 final name = 'Bob'; // Or: final String name = 'Bob';
 name = 'Alice';     // ERROR
 {% endhighlight %}
 
 #### Summary
 
 Although Dart variables are optionally typed,
 we generally recommend using types
 because they make your intent clear.
 Variables can be marked as `final`, locking the value. Uninitialized variables
 have an initial value of `null`.
