easy_localization - using new line - \n in a String - flutter

Question

In my Flutter Project I'm using the package easy_localization (https://pub.dev/packages/easy_localization).
I wan't to use Strings like this: This is my Test String.\nIt is supposed to be separated by a new line!.
easy_localization is ignoring the \n and simply shows it as the characters \n and not doing a real new line. A flutter string usually knows what is meant by a \n and interpret it correct.
How do I archive that a \n still get's interpreted as a new line?
Edit:
My localization files are xml files that are kinda like this:
<?xml version="1.0" encoding="UTF-8" ?>
<root>
<my_string_key>This is my Test String.\nIt is ... by a new line!</my_string_key>
</root>
And I call it somewhere as tr("my_string_key")
Edit:
My Solution now is just that I created a file my_localizer.dart that only got this function:
String myTr(String key) { return tr(key).replaceAll("\\n", "\n"); }
I could import it at the files that I needed it and can use it exactly like the original tr():
myTr("my_string_key")

You can use the replaceAll method on the string to replace the \n with a newline character (\n) before passing it to the easy_localization package. Here's an example:
String myString = "This is my Test String.\nIt is supposed to be separated by a new line!";
String localizedString = AppLocalizations.of(context).tr(myString.replaceAll("\n", "\n"));
This will replace all instances of \n in the string with actual newline characters, so that the string will be displayed as intended when passed through the easy_localization package.
