NoSuchMethodError: The method 'get' was called on null.

[maxa11an]

So I tried to use this for a new project I'm working on. Yet it is basically just the default app. However it throws below error.

The relevant error-causing widget was: 
MyHomePage file:///Users/maxallanniklasson/vipmonkey/_dev/app_flutter_public/lib/main.dart:24:13
When the exception was thrown, this was the stack: 
#0      Object.noSuchMethod (dart:core-patch/object_patch.dart:53:5)
#1      Localization._resolve (package:easy_localization/src/localization.dart:100:48)

Also, strange things happen on change locale - if i try to change locale to Locale('he'), i see in console that locale was changed to 'he_IL', but right after it another message with locale 'he_US'

PS: In version 1.4.1 - everything work fine (except issue with current page translations on locale change)

@maxa11an u have a file naming error use - not _

    - resources/langs/sv_SE.json # to sv-SE.json

    - resources/langs/sv.json
    - resources/langs/en.json

@Laim0n about ur code i fixed check RPs this

@psycura plz check JSON file probably wrong file or wrong name

[psycura]

@psycura plz check JSON file probably wrong file or wrong name

I think you wrong, because i use same jsons, that use with 1.4.1. I think that this issue is related to parameter useOnlyLangCode: true, I think plugin still try to seek locales by 'langCode_coutryCode'
