NoSuchMethodError: The getter 'pressback' was called on null

[AlecSPb]

My code:

My screen:

When I write the code: content: Text ("Press back again to exit",), that works.
How do you use this in your application locales?

I18n.of(context) returns null, so I cannot see how this package influences in this error. As such, if you remove DoubleBackToCloseApp, the error should remain. Try this:

body: Center(
  child: Text(I18n.of(context).pressback),
),

Probably there's something wrong about your i18n set up :)

[AlecSPb]

body: Center(
  child: Text(I18n.of(context).pressback),
),

This code is't work.
I also tried the Intl plugin. The same error crashes

body: Center(
    child: Text(S.of(context).homeScreenDoubleBackToCloseAppSnackBarText)),

This code is't work.

As expected. Therefore, your issue is not related to DoubleBackToCloseApp.

Please check your internationalization set up.
