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

In this lesson, you'll work on a challenge that will test your understanding of animations.

# Goal
Understand how to create a forever-repeating animation.

# Specs
The heart icon should animate in size from small, size 16, to large, size 24, to small again continuously.

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

description: A new Flutter application.

# The following line prevents the package from being accidentally published to
# pub.dev using `flutter pub publish`. This is preferred for private packages.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

# Dependencies specify other packages that your package needs in order to work.
# To automatically upgrade your package dependencies to the latest versions
# consider running `flutter pub upgrade --major-versions`. Alternatively,
# dependencies can be manually updated by changing the version numbers below to
# the latest version available on pub.dev. To see which dependencies have newer
# versions available, run `flutter pub outdated`.

  # The "flutter_lints" package below contains a set of recommended lints to
  # encourage good coding practices. The lint set provided by the package is
  # activated in the `analysis_options.yaml` file located at the root of your
  # package. See that file for information about deactivating specific lint
  # rules and activating additional ones.
  flutter_lints: ^1.0.0

# For information on the generic Dart part of this file, see the

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #   - images/a_dot_burr.jpeg
  #   - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700

# Challenges
You will implement the challenges in the `contacts_list_screen.dart` file.

We want the heart icon to simulate a beating heart. The size should animate by transforming from small (size 16) to large (size 24) to small again continuously.

## Challenge 1: Add `TickerProviderStateMixin`


1. Locate `// TODO: CHALLENGE #1 - add TickerProviderStateMixin to the widget state class`.
2. Add `TickerProviderStateMixin` to the widget state class.


Test your understanding of adding animations to your app.
