[Feature]: Localization - Add support for English & Hindi

[VJLIVE]

What's the problem this solves?

Adding language support will help the people read and use our app who are good in hindi

Proposed Solution

🌐 Feature Request: Add Localization Support (Flutter)

We need to implement localization (i18n) in the Flutter app to support multiple languages, starting with:

• 🇬🇧 English (default)
• 🇮🇳 Hindi

---

📋 Tasks

• Add flutter_localizations and intl packages
• Enable localization support in MaterialApp
• Create ARB files for supported languages:
  • lib/l10n/intl_en.arb
  • lib/l10n/intl_hi.arb
• Extract translatable strings using Intl.message() or @GenerateLocalization
• Generate localization files using flutter gen-l10n
• Implement UI logic for language switching (if needed)
• Test switching between English and Hindi
• Update README.md with instructions for contributing new translations

---

📦 Example: Add to pubspec.yaml

dependencies:
  flutter_localizations:
    sdk: flutter
  intl: ^latest

I have completed the localization,switching and documentation parts , but i can't test the screens connected to Firebase due to the null value check and some of which are incomplete.

[VJLIVE]

null check value in the auth_screen?

[DotDev262]

No, in the financial tracker, injury tracker, .. etc
