translateBlocMessage function

String translateBlocMessage(dynamic localizations, String messageKey, { Map<String, dynamic>? params, })

Translates a BLoC message key to a localized string using the provided localizations object.

This function provides a clean separation between BLoC (business logic) and UI (localization). BLoCs emit message keys, and the UI layer translates them using this helper.

Usage:

BlocListener<UserBloc, UserState>(
  listener: (context, state) {
    if (state.status == UserStatus.success && state.message != null) {
      final localizations = UserCompanyLocalizations.of(context)!;
      HelperFunctions.showMessage(
        context,
        translateBlocMessage(localizations, state.message!),
        Colors.green,
      );
    }
  },
  child: // ... your UI
)

Parameters:

• localizations: The localizations object (e.g., UserCompanyLocalizations, CoreLocalizations)
• messageKey: The message key to translate (e.g., 'userUpdateSuccess')
• params: Optional map of parameters to replace in the translated message

Returns: The translated string, or the original key if no translation is found

Implementation

String translateBlocMessage(
  dynamic localizations,
  String messageKey, {
  Map<String, dynamic>? params,
}) {
  try {
    // Use a type-safe approach without using mirrors
    String? translatedMessage = _getTranslationFromLocalizations(
      localizations,
      messageKey,
      params,
    );

    return translatedMessage ?? messageKey;
  } catch (e) {
    debugPrint('Translation error for key "$messageKey": $e');
    return messageKey; // Fallback to the key itself
  }
}
