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: "Now that you have finished updating the pubspec.yaml file, save the changes."

A block of code is set as follows:

void main() async {

  final goldRush = GoldRush();

  WidgetsFlutterBinding.ensureInitialized();

  await Flame.device.fullScreen();

  await Flame.device.setPortrait();

  runApp(

    GameWidget(game: goldRush)

  );

}

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

cd build/web/

python3 -m http.server 8000 &

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: "The Game Over!! screen will be shown when the player dies in the game and then they return to the game menu."
