Not work ionic-native

Ionic Framework ionic-v3
1

Hello.

I have a problem.

  1. I use example (http://ionicframework.com/docs/v2/native/toast/):
    ionic plugin add cordova-plugin-x-toast

and use code:
Toast.show("I'm a toast", '5000', 'center')

But not visible image.

2.I use (http://ionicframework.com/docs/v2/native/keyboard/)
ionic plugin add ionic-plugin-keyboard

and code

platform.ready().then(() => {
Splashscreen.hide();

    Keyboard.disableScroll(true);
    Keyboard.hideKeyboardAccessoryBar(true);

});

It is not work.

If i add in config.xml <preference name="HideKeyboardFormAccessoryBar" value="true"/>
it work correctly.

I build ipa with ionic.io (ionic package build …)
