Overview of this book

There have been many attempts at creating frameworks that are truly cross-platform, but most struggle to create a native-like experience at high performance levels. Flutter achieves this with an elegant design and a wealth of third-party plugins, making it the future of mobile app development. If you are a mobile developer who wants to create rich and expressive native apps with the latest Google Flutter framework, this book is for you. This book will guide you through developing your first app from scratch all the way to production release. Starting with the setup of your development environment, you'll learn about your app's UI design and responding to user input via Flutter widgets, manage app navigation and screen transitions, and create widget animations. You'll then explore the rich set of third party-plugins, including Firebase and Google Maps, and get to grips with testing and debugging. Finally, you'll get up to speed with releasing your app to mobile stores and the web. By the end of this Flutter book, you'll have gained the confidence to create, edit, test, and release a full Flutter app on your own.

Releasing your app on Android

In Android, appbundle is the format expected to be published in the Google Play Store. When we run the flutter build appbundle command, we generate the file ready for deployment.

You may have previously seen the Android APK (short for Android application package) option instead of the appbundle. Releasing your app as an APK has been deprecated by Google as an option on the Play Store, and will be fully withdrawn soon. Under the covers, an appbundle effectively generates APKs for devices but hides that complexity away.

Before we generate the file for deployment and publishing in any store, we need to make sure all of the information is correct (that is, the name and package), all needed assets are provided, and all platform-specific adjustments are made.

Let's start by preparing our HelloWorld app for release on Google Play so that we can review all of the final steps of publishing a Flutter app.
