The app uses a design system: Chai

Dependencies

The project uses Versions Catalog to set up and share dependencies across the modules. The main reasons for choosing to adopt Versions Catalog are:

• Central place to define dependencies.
• Easy syntax.
• Does not compromise on build speeds as changes do not need the module to be compiled.

To add a dependency, navigate to gradle/libs.versions.toml* file, which has all the dependencies for the whole project. This file has the following sections:

[versions] is used to declare the version numbers that will be referenced later by plugins and libraries. [libraries] Define the libraries that will be later accessed in our Gradle files. [bundles] Are used to define a set of dependencies. For this, we have compose, room, lifecycle and ktor as examples. [plugins] Used to define plugins.

You need to add your dependency version in [versions]. This is unnecessary if you are not sharing the version across different dependencies. After defining the version, add your library in the [libraries] section as:

compose-activity = "androidx.activity:activity-compose:1.5.0"

Moreover, if you have already defined the version in [versions], you define it as:

androidx-splashscreen = { module = "androidx.core:core-splashscreen", version.ref = "splash" }

Note:

• You can use separators such as -, _v, . that will be normalized by Gradle to . in the Catalog and allow you to create subsections.
• Define variables using CamelCase.\
• Check if the library can be added to any existing bundles.

Material 3 Bottom Sheets

At the time of working on this app, Material 3 didn't have BottomSheet classes. Solution was to copy them from AOSP. They can be found in the com/android254/presentation/common/bottomsheet packages and have been used to do the Share feed and Fitter Bottom Sheets. You can find more information here.
