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: “For example, in the build.gradle file of the :app module, include the following code in the dependencies section.”

A block of code is set as follows:

class MessagesRepository @Inject constructor(    private val dataSource: MessagesSocketDataSource ): IMessagesRepository {    override suspend fun getMessages(): Flow<Message> {        return dataSource.connect()    }

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

Scaffold(
    topBar = {
        TopAppBar(
            title = {
               Text(stringResource(R.string.chat_title,
               uiState.name.orEmpty()))
            }
        )
    },

Bold: Indicates a new term, an important word, or words that you see on screen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “Android Studio will offer us a set of templates to start with. We will choose the Empty Activity option, as shown in the following screenshot:”
