Kotlin

Q1: What is a primary constructor in Kotlin? ☆☆

Answer: The primary constructor is part of the class header. Unlike Java, you don't need to declare a constructor in the body of the class. Here's an example:

BindingScoped.kt

@Scope
@Retention(AnnotationRetention.BINARY)
annotation class BindingScoped

CustomBindingComponent.kt

lifecycleScope.launch {
    repoAdapter.loadStateFlow.collect { loadState ->
        // Show a retry header if there was an error refreshing, and items were previously
        // cached OR default to the default prepend state
        header.loadState = loadState.mediator
            ?.refresh
            ?.takeIf { it is LoadState.Error && repoAdapter.itemCount > 0 }
            ?: loadState.prepend

        val isListEmpty = loadState.refresh is LoadState.NotLoading && repoAdapter.itemCount == 0
