Learn Flutter, Grep and Reactfire

Flutter allows you to build native apps on iOS and Android from a single codebase. In this course, we'll walk through everything you need to know to quickly get up & running with Flutter including styling, navigation, local state management, theming, lists & forms.

CMD+F in your text editor can only get you so far! In this course, we will learn to use grep and find, two powerful command-line utilities, to search through and explore our codebase. Learn to search specific files and folders, using regular expressions to look for -- or ignore! -- particular phrases. We'll cover how to search recursively, get more context on your results, and some simple tricks to make your searches faster and more targeted.


Once you're familiar with grep and find, you'll be able to quickly answer questions such as: Do I use this function anywhere other than my tests? Where does this file get imported? Whether you're working on a new feature, reading a codebase for the first time, or refactoring existing code, grep and find can help you work faster and more effectively.

A Unix command used to search files for the occurrence of a string of characters that matches a specified pattern.

In this lesson, we will cover Interfaces and Mixins. Interfaces act as a contract containing properties and methods that a class must define once it “implements” this interface. Mixins are Dart’s way of sharing properties and methods from multiple classes, since by design Dart adopts a single-inheritance model.

Define Interfaces and Share Class Members through Mixins in Dart

Futures represent a computation that does not complete immediately. Where a normal function returns a result, an asynchronous function returns a Future that will eventually contain the result. These are similar to Promises in JavaScript. In this lesson, we will learn how to program asynchronously by writing logic to capture values that are returned at a later time.

In this lesson we’ll learn how to run a Flutter project on an iOS Simulator.

In this lesson we’ll learn how to style Text & Container widgets & also get a general understanding of how styling works in Flutter applications

Style a Flutter Text and Container Widget

In this lesson, we’ll learn how to download & install the Flutter CLI from the Flutter website. We’ll then use the Flutter CLI create our first Flutter project.

Install the Flutter SDK & Create Your First Project

In this lesson we’ll walk through the example project that the Flutter CLI created for us & discuss the files & folders that were created for us.

In this lesson we’ll learn how to use themes in order to share colors and font styles throughout our application.

Using Themes in Flutter to Share Colors and Font Styles

In this lesson we’ll learn how to render both local & network images in a Flutter application using the Image class.


Load an Image in a Flutter App with the Image Class

Streams represent a sequence of asynchronous events. Each event is either a data event, also called an element of the stream, or an error event, which is a notification that something has failed. When a stream has emitted all its events, a single "done" event will notify the listener that the end has been reached. In this lesson, we will learn how we can capture and handle streaming data, working with various Stream classes.

In this lesson we’ll learn about the main layout widgets you'll need when building your user interface in Flutter. We’ll take a look at Container, Center, Row, Column, Stack, & GridView widgets learn how they work.

Building Layouts in Flutter with Layout Widgets

In this lesson we’ll learn how to import widgets we’ve created in other files & use them in our project. We'll also look at how to create dynamic properties in our widgets in order to make them reusable across our application.

In this lesson we’ll learn how to create & update state in a Flutter application.

In this lesson we’ll learn how Navigation in Flutter works by navigating to a new page when clicking on a button using the push & pop methods. We'll also look at how to pass properties to a new screen dynamically.

Getting Started with Navigation in Flutter

In this lesson, we'll learn how to specify a configuration object containing all of the routes for our application & navigate between them in a Flutter application.

ListView is the most commonly used scrolling widget in a Flutter application. In this video, we'll learn how to create dynamic lists using Flutter's ListView widget to render both lists of Strings & lists of Maps

Building Dynamic Lists in Flutter with ListViews

In this lesson we’ll learn how to fetch & then display data from an API over the network in a Flutter application using the http package.

Fetching & Displaying Data from an API in Flutter using the http Package

When you have a bunch of text to sift through, standard Unix command line utilities like `grep`, `sed`, `awk`, `cut`, `sort`, and `uniq` can help extract the information you want. For example, with a git log for a project, you might want to group commits by day in order to see which days you're most productive, or find out how many commits you made last year. In this lesson, you'll learn how to combine these commands with the pipe operator to extract this data from git logs.

Analyze Git Logs with the Command Line

Pub is a package management tool that makes it easy for you to install, use, share Dart libraries, command-line tools and other assets. It comes as part of the Dart SDK, and requires a dependency file called pubspec.yaml.
