Wrapping up

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.

After completing Line-of-Business Apps with Flutter 3, developers have the skills to build mobile apps backed by their
choice of server technologies, taking advantage of the incomparable performance, speed-to-value, and developer
experience of Flutter and Dart.

Bring your mobile app ideas to life on every device

### 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.

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

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.

Great work! If you've made it this far, you know how to write Flutter apps that:

-   Use a single codebase
-   Deploy to iPhone, Android, and desktop computers
-   Look great on screens of any size
-   Are accessible to blind and vision-impaired users
-   Communicate with any server that uses HTTP endpoints
-   Use multiple kinds of layouts and interactive elements
-   Display useful tables, charts, and graphs
-   Include custom drawings and animations
-   Are tested at the unit, widget, and end-to-end level
-   Are incredibly fast and nearly indistinguishable from native apps
