/// This example demonstrates basic translations using a `I18n` widget.
///
/// There are 3 widget files that need translations:
/// * main.dart
/// * my_screen.dart
/// * my_widget.dart
///
/// And there is one translations-file for each one:
/// * main.i18n.dart
/// * my_screen.i18n.dart
/// * my_widget.i18n.dart
///
/// Note: We could have put all translations into a single translations-file
/// that would be used by all widget files. It's up to you how to organize
/// things.
///
/// Note: The translations-files in this example use strings as keys.
/// For example:
///
///     "You clicked the button %d times:".plural(counter),
///
