Get ready to unlock the potential of Flutter and Dart as you learn to craft visually stunning and high-performance applications for both Android and iOS.

This course will teach you to plan, build, and deploy interactive Flutter applications. You’ll start by developing user interfaces and handling gestures. Next, you’ll explore navigation and routing to smoothly move around your app. You’ll then dive into networking and HTTP to connect your app to the internet and implement data persistence. You’ll use Firebase services for authentication and storing data. State management comes next, helping you manage the different pieces of your app efficiently. Then, you’ll focus on testing, analytics, and crash reporting. You’ll then explore accessibility and internationalization, making your app usable by everyone and suitable for different languages. Lastly, you’ll learn app deployment.

The course wraps up with a project: you will create an online furniture store, combining all the skills you’ve learned.

The Complete Guide to Flutter



# Goal

This challenge aims to help you understand how code generation works using the `json_serializable` library to generate JSON serialization boilerplate. You will learn to use the official documentation of the packages. 

# Specs

When you run your app and navigate to "Realtime Transactions," a list of transactions streams in, except this time, you are fetching serialized data:

# Starter code
Before you begin the challenge, look at the starter code below and run it.
Once done, you can dive into the challenges below.

# Challenges


## Challenge 1: Set up `json_serializable`

To make use of `json_serializable`, you'll need to include one dependency, [`json_annotation`](https://pub.dev/packages/json_annotation), and two dev dependencies, [`build_runner`](https://pub.dev/packages/build_runner), and [`json_serializable`](https://pub.dev/packages/json_serializable), in your `pubspec.yaml` file.

1. Locate `# TODO-1: Add dependency`, and `# TODO-2: Add dev dependencies` in the `pubspec.yaml` file and add the required packages. 
2. Run the app to get the dependencies.

## Challenge 2: Modify model classes in the `json_serializable` way
You'll now convert your `Transactions` model class to use `json_serializable`.

1. Locate `// TODO-3: Add annotation` in `lib/models/transactions.dart` and add the `@JsonSerializable()` annotation to the class. Don't forget to import the `json_annotation` package. 
2. Locate `// TODO-4: Add fromJson helper` in `lib/models/transactions.dart` and create a `fromJson` helper. 

Here's a sample `fromJson` helper:
