If you're starting a new project and want to use Kotlin, see Including autocomplete, lint checking, refactoring, debugging, and more. You can then use all of Android Studio's existing tools with your Kotlin code, Kotlin files to your existing project and convert Java language code to Kotlin. Here’s an example - marking the color parameter is normal in this case.Android Studio provides full support for Kotlin, enabling you to add The most common way you’ll encounter the first case is MaterialTheme as default on your composables. The most common use case for this is state hoisting. *You are explicitly calling a composable function, such as remember. In these cases, you need to rely on the fact that the default expression will be re-executed when the value changes. Composition Locals and state variables are an important example of this. * You are explicitly reading an observable dynamic variable. This is a great tool to find potential performance issues.įirst step is to configure the metrics - to do this, add the following to your adle file: subprojects Īnother thing we need to pay attention to is default parameter expressions that are documentation says:ĭefault expressions should be in every case except for the following two cases: In Jetpack Compose 1.2.0, a new feature was added to the Compose compiler that can display various performance metrics during the build. You will see how to gather information with metrics and how it can in with fixing performance issues. While the previous parts ( Part 1, Part 2, Part 3, Part 4) focused on implementing complex UI and animations, this part will be about Compose compiler metrics. This is the fifth and last part of the Compose dribbble Replicating series. We started with SwiftUI some years ago, but this is our first foray into Android, using Google’s declarative UI framework: Jetpack Compose. One type of tutorials we do is replicating - taking a complex UI component, implementing it using new frameworks and writing a tutorial alongside.

At Exyte we try to contribute to open-source as much as we can, from releasing libraries and components to writing articles and tutorials.
