Flutter is Google's mobile UI framework for crafting high-quality native interfaces on iOS and Android. Flutter applications are written using the Dart programming language, which has helped make Dart a beloved language by the developer community. Before you can start fluttering out Flutter applications, you must learn Dart. This course will help you learn the fundamentals of Dart and start your journey to learning Flutter.

Learn Dart: First Step to Flutter

## What are data types?

The data type of an item or variable is an attribute that tells us what kind of data that variable can have.

Data types can be found all around us; numbers, alphabets, or characters which are classified based on the similar properties they share. 

## Dart’s built-in data types

The Dart language has special support for the following types:

  

* Numbers
* Strings 
* Booleans
* Lists
* Sets
* Maps
* Runes
* Symbols

The focus of this chapter will be numbers, strings, and booleans. Lists, sets, and maps are topics for another chapter. Runes and symbols are beyond the scope of this course.

Before we can move on to each data type in detail, there are a couple of things you should familiarize yourself with. 

## Values and references

Data types can be broadly divided into two categories:

1. **Reference type** 
2. **Value type**

The information provided by a value type is the *value* itself. For a reference type, the information it provides is a *reference* to some object, i.e., the *memory address* of where an object is stored. To make this clearer, let's look at this using physical objects.
