The above info is not enough info for me to see what's going on. It just tells me the locale is null. Please, provide me with a single file with a minimum runnable example, including the main method.

However, I would guess, since the locale is unknown, that you forgot to wrap your widgets with I18n(child: ...). Please make sure you are doing this:

@override
Widget build(BuildContext context) {
 return MaterialApp(
   home: I18n(child: ...)
 );
}

I have the same error. UsingText("Hello there".i18n) and my_widget.i18n.dart file

[weraaaaz]

Ok, fixed by adding @override Widget build(BuildContext context) { return MaterialApp( home: I18n(child: ...) ); } . It wasn't very clear in docs that you need this if you use translatable strings

[marcglasberg]

@weraaaaz I'll make it clearer in the docs.
