Get Started

First of all, let's import the extensions with:

import 'package:awesome_flutter_extensions/awesome_flutter_extensions.dart';

Usage

There are many extensions in this library. So I decided to break them up into groups. The groups currently available are:

• sizes
• textStyles
• colors
• themes
• platform
• string
• navigator
• miscellaneous

Why this split? After creating extensions upon extensions, I admit that with context you could access an infinite number of things. That's why I decided to split them up.
