Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "Inside the resources folder, create a subfolder called mockito-extensions. Inside this folder, create a file named org.mockito.plugins.MockMaker, and inside this file, add the text mock-maker-inline."

A block of code is set as follows:

data class User(
    val id: String,
    val firstName: String,
    val lastName: String,
    val email: String
) {
    fun getFullName() = "$firstName $lastName"
}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

…
@Composable
fun Screen(viewModel: MainViewModel = viewModel(factory = MainViewModelFactory())) {
    viewModel.uiStateLiveData.observeAsState().value?.let {
        UserList(uiState = it)
    }
}
…

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "Create a new project in Android Studio using an Empty Compose Activity."
