The idiomatic way of naming constants in Compose is using PascalCase. That seems obvious for object declarations, but we also use this convention for immutable top-level properties (including those with const modifier) and for enum values. That gives us consistency between all the different ways of representing constants.

Kotlin Coroutines offer a powerful way to handle asynchronous programming, but using them effectively in production requires a solid understanding of best practices. In this insightful talk, Marcin Moskala explores real-world coroutine patterns to help you write efficient, maintainable, and scalable code.

Modifier builders or resources that are used for many composables can be extracted for better performance. Why make something many times, if you can create it only once 😎

If you need to persist identity of a component that changes place, that can be achieved with movableContentOf. It allows using the same composable objects as children of different parents. That is especially useful when we define adaptive layouts.

Prefer lambda modifiers for frequently changing state❗Why? Because this way we limit recomposition scope. If we read state when we build modifiers, this scope change triggers whole this composable recomposition, and requires building modifiers again. If we read state in a composable lambda, only this lambda will get recomposed with scope change 👌

Incredible how the time flies!

If you are not sure about stability of your classes and parameters, you can use Compose compiler report 📈 It generates a report showing how each class and parameter is treated, and essential statistics related to stability 🔍

Here is a very practical example of yield function. In my game, I use a very complex function to generate challenges. It can take a couple of seconds. If this function is started on the same thread as UI, application would be frozen. In Android the simplest solution is to start it on Dispatchers. Default, but that is not useful on JS. So making it suspending and adding yield, to give space for UI updates, is the only option.

String skipping mode is enabled by default since Kotlin 2.0.20❗Its two biggest changes are that 1. composables with unstable parameters are skippable, they are skipped if equal arguments are used (compared with === for unstable types, and with == for stable), 2. all lambdas in composables are remembered by default.

When you use by keyword after a property, you delegate getter to getValue and (if var) setter to setValue from the delegate. Those functions can be extensions, like in State, where they only read or write value property.
