Howto: missingKeyCallback about i18n_extension

[marcglasberg]

You may set up callbacks that the i18n_extension package will call whenever it detects a missing translation. You can then program these callbacks to throw errors if any translations are missing,
or log the problem, or send emails to the person responsible for the translations.

How to use this? Just write this in your app's initialization code:

Translations.missingKeyCallback = (key, locale) { [write some function that uses the missing key and locale here] }

Translations.missingTranslationCallback = (key, locale) { [write some function that uses the missing key and locale here] }

where do I add this? can you please update sample app to show how to disable this?
I have settings page from where I change locale, It used to work perfectly before new flutter and this package update, Not when I try to translate it some times works sometimes not. I have to go back and forth on that page to get translations working.

@ManojMMWWIndia That's kind of serious. I haven't had other reports about anything changing with Flutter 1.17. Could you please create an example that demonstrates the problems you are having?
