tr function

String tr(String key, { BuildContext? context, Map<String, dynamic>? namedArgs, int? count, })

Translates a key into a localized string.

• key: The key for the localized string.
• context: Optional build context for locale resolution.
• namedArgs: Optional named arguments for string formatting.
• count: Optional count for pluralization.

Implementation

String tr(String key,
    {BuildContext? context, Map<String, dynamic>? namedArgs, int? count}) {
  // Early return if no special formatting or pluralization is needed
  if (namedArgs == null && count == null) {
    return key.tr(context);
  }

  // Handle pluralization
  String result = count != null ? key.trPlural(count) : key;

  // Apply named arguments if any
  if (namedArgs != null) {
    result = result.trParams(namedArgs);
  }

  return result.tr(context);
}
