السلام عليكم
ممكن توضيح لx liff ؟ للغة العربية

Turkish Translation

For the strings that use booleans variables, I did two types of strings for the true and false. For order_summary_whipped_cream and order_summary_chocolate I got rid of the xliff:g and used this code:
English

<!--
    Whipped cream topping for the order summary. It will be shown in the format of
    "Add whipped cream? true" or "Add whipped cream? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_whipped_cream_true">Add whipped cream? true</string>
<string name="order_summary_whipped_cream_false">Add whipped cream? false</string>

<!--
    Chocolate topping for the order summary. It will be shown in the format of
    "Add chocolate? true" or "Add chocolate? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_chocolate_true">Add chocolate? true</string>
<string name="order_summary_chocolate_false">Add chocolate? false</string>

`Spanish

<!--
    Whipped cream topping for the order summary. It will be shown in the format of
    "Add whipped cream? true" or "Add whipped cream? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_whipped_cream_true">Agregue la crema batida? verdadero</string>
<string name="order_summary_whipped_cream_false">Agregue la crema batida? falso</string>

<!--
    Chocolate topping for the order summary. It will be shown in the format of
    "Add chocolate? true" or "Add chocolate? false". [CHAR LIMIT=NONE]
-->
<string name="order_summary_chocolate_true">Agregue el chocolate? verdadero</string>
<string name="order_summary_chocolate_false">Agregue el chocolate? falso</string>

Then in the java file, I used the conditional operator, ?:, to set the values.to the boolean variables.
