Request for Dzongkha (dz) Locale Support in `intl` Package

[kinleyrabgay]

Hello Devs,

I am requesting the addition of Dzongkha (dz) as a supported locale in the intl package for Flutter. Dzongkha is the official language of Bhutan, and it would be great to have proper localization support for this language.

Currently, Flutter’s built-in localization delegates (MaterialLocalizations, CupertinoLocalizations, etc.) do not provide support for Dzongkha. As a result, developers targeting Bhutanese users have to manually create custom localization for Dzongkha, which is an extra step.

I believe adding this locale to the intl package will improve the overall experience for developers and ensure that Flutter supports Bhutanese users.

Suggested Changes:

• Add the Dzongkha (dz) locale to the list of supported locales in the Flutter intl package.
• Ensure that built-in delegates such as MaterialLocalizations and CupertinoLocalizations have necessary support for Dzongkha.
• Provide example translations for common Flutter UI elements (e.g., buttons, tooltips, date formats, etc.).

Why this is important:

• Dzongkha is the official language of Bhutan, and it is widely used for government, education, and daily communication.
• Flutter currently has limited support for smaller locales like Dzongkha, making it difficult for developers to build apps for Bhutanese audiences without custom localization solutions.
• The addition of Dzongkha support will help extend Flutter’s reach and usability in Bhutan, as well as for the Bhutanese diaspora.

Thank you for considering this request. I look forward to your feedback!

Example code:

Locale('dz') // Dzongkha locale
