🧠 Why use this?

• Centralizes all date/time format strings in one place.
• Improves consistency, reusability, and maintainability.

📦 Usage

import 'package:intl/intl.dart';

final formatted = DateFormat(DateTimeFormatsVN.dateOnly, 'vi_VN').format(DateTime.now());
print(formatted); // e.g., 26/03/2025
