Conventions used

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

Code in text: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Then, in the main.dart file, first import firebase_core and firebase_options.dart generated by flutterfire_cli.”

A block of code is set as follows:

Future<bool> anonymousLogin() async {
  if (isLoggedIn) {
    error = 'Already logged in';
    return false;
  }
}

Any command-line input or output is written as follows:

flutter pub get

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: “Click on the Start new project button.”
