Next, create an assets directory at the top of the project tree, and fill it with a series of images from the git repository for this codelab. These images represent the users, and are referred to as avatars. You can also choose to run it in Android, iOS, or your desktop operating system.Įvery messaging application needs images of its users.

Depending on which toolchains you have installed, and whether you have simulators or emulators running, you might be asked to decide which deployment target to run the application on. You can run this code, either through your code editor, or directly from the command line. ![]() Your empty application code is in animated_responsive_layout/lib/main.dart.

Some of these deployment targets require additional software installed to be able to deploy to. This codelab has been tested to deploy on Android, iOS, the web, Windows, Linux, and macOS. An editor, for example VS Code, or Android Studio.Non-relevant concepts and code blocks are glossed over and are provided for you to simply copy and paste. This codelab is focused on Material 3 with Flutter. Run on Android, iOS, the web, Windows, Linux, and macOS.Use animation to easily and fluidly switch between different layouts.Use adaptive design, so it works on desktop or mobile.In this codelab, you're going to build a mock messaging application. In this codelab you start with an empty Flutter application and build out a fully styled and animated application using Material 3 with Flutter. Flutter has been expanding support for building beautiful applications using Material 3. Material 3 is the latest version of Google's open-source design system.
