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: "If you have already cloned or downloaded the repository of this book, its project folder is located inside chapter_01."

A block of code is set as follows:

@Composable 
fun Greeting(name: String) { 
  Text( 
    text = stringResource(id = R.string.hello, name), 
    textAlign = TextAlign.Center, 
    style = MaterialTheme.typography.subtitle1 
  ) 
}

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

TextField( 
  value = name.value, 
  onValueChange = { 
    name.value = 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: "After you have entered your name and clicked on the Done button, you will see a greeting message."
