11. Using Plurals in your Dart String.

Plurals: Different languages have different rules for grammatical agreement with quantity. In English, for example, the quantity 1 is a special case. We write "1 book", but for any other quantity we'd write "n books". This distinction between singular and plural is very common, but other languages make finer distinctions.

You can use Plurals in your Dart string by using Intl package. The full set supported by Intl package is zero, one, two, few, many, and other.

  • Add dependency:
  intl: version
  • How to use:
import 'package:intl/intl.dart';
notificationCount(int howMany) => Intl.plural(
      zero: 'You don\'t have any notification.',
      one: 'You have $howMany notification.',
      other: 'You have $howMany notifications.',
      name: "notification",
      args: [howMany],
      examples: const {'howMany': 42},
      desc: "How many notifications are there.",

  • Output:
You don't have any notification.
You have 1 notification.
There are 2 notifications.

9. Want to log data on the system console in Flutter?

You can use the print() function to view it in the system console. If your output is too much, then Android sometimes discards some log lines. To avoid this, you can use debugPrint().

You can also log your print calls to disk if your doing long-term or background work.
