Line-of-Business Mobile Apps with Flutter and Dart

In this course you'll build a corporate app and package it for iPhone and Android from a single codebase.

Flutter is a popular and feature-rich multi-platform development toolkit, but it's got some surprises for traditional web and desktop developers. You'll learn how to think in the Flutter way and build fast, maintainable, visually appealing apps.

What You Will Build In This Course

Course Overview

Build cross-platform iOS and Android apps faster than you thought possible

What you will learn
  • How to build and package apps for iOS and Android from a single codebase

  • Why Flutter and Dart are a perfect match for multi-platform apps

  • Where to start building with Flutter

  • The Flutter paradigm for layout and components

  • How to keep your Flutter app fast and responsive

  • State management, server requests, accessibility, and more

Build Better Mobile Apps with Flutter

Smartphones are the most popular computing devices in the world, and mobile apps are the best way to reach technology consumers. But building fully native apps means learning two or more completely different sets of programming languages, UI frameworks, layout systems, and developer toolkits. Other cross-platform frameworks have tried to make this process easier, but none of them have achieved the popularity, performance, or resilience of Flutter.

With Flutter, you'll avoid several problems you may have had with other app frameworks:

  • Publish native app packages for iOS, Android, Windows, macOS, and Linux, all from a single codebase, without writing a single line of native code.
  • Write faster, safer code with the familiar syntax, type safety, and null safety of the Dart programming language.
  • Flutter is an all-in-one component library and toolkit: spend your time building components and writing application logic instead of fiddling with toolchain configuration and searching for 3rd-party packages.
  • Never worry about the way your app looks on different devices; with Flutter's built-in rendering engine and logical pixel scaling, your app will look the same on every screen, everywhere.

Be Prepared for Any Challenge

Flutter is an easy-to-learn, top-rated technology for developers, but it doesn't come without gotchas. In this course, you'll learn to breeze right through some of the hardest parts of Flutter development:

  • Responsive design, complex layouts, and breakpoints
  • Layout errors and infinite constraints
  • Hand-drawn components
  • Custom animations, tickers, and tweens
  • State management and data persistence

Start Building Real Apps Faster

This course won't waste any time teaching you what an if statement is. You'll be able to use the programming experience you already have and jump straight into building mobile apps with Dart and Flutter.

Along the way, you'll build skills you can use immediately for any app you dream up:

  • By the end of Module 2, you'll have already packaged a Flutter app for distribution on the iOS and Android app stores.
  • By the end of Module 3, you'll have a seed app you can use for any project.
  • By the end of Module 4, you'll know how to build responsive layouts and use the most common types of widgets.
  • By the end of the course, you'll have built an accessible, interactive, server-backed app with custom animations and three types of automated tests.

Along the way, you'll discover Flutter's secret: it's not only the easiest way to build cross-platform mobile and desktop apps, it's the easiest way to deliver any* kind of technological experience, period**. Not even the web, with its variety of frameworks and tools, can match the development speed and polished UI of a Flutter app.

Course Syllabus and Content

Flutter is a popular cross-platform development framework. It's packed with off-the-shelf features and focused on developer ergonomics, which means you can build faster and deploy to more platforms with fewer dependencies. Some parts of the framework will catch you by surprise, though, especially if you're used to developing for the web or writing native apps. This course will walk you through the creation of a Flutter app from setup to final package and help you develop a mental model that will carry you through the most common problems Flutter devs encounter.

By the end of these 10 modules you'll have built:

  • A Flutter seed project that can manage state, swap out color palettes, and handle deep links
  • An accessible, error-resistant profile page that fetches data from a web API
  • A responsive data table and data-driven visualizations
  • A complete app ready to deploy to iPhone and Android

This course includes sample code, explained step-by-step, that you can reuse for any Flutter app you build.

It's taught by Isaac Lyman, author of Your First Year in Code and Top 10 Author on The DEV Community.
