Ionic Native Push

Hi everyone!
I try use @ionic-native/push tu use push notification from Firebase. The notification is works like i want, except for funciton createChannel. I try use that, because Android 8 needs that channel to works fine (I supose).
I dont know why, but ever i try use this function, my console return:
Warning => Native: tried calling Push.createChannel, but the Push plugin is not installed.
Install the Push plugin: ‘ionic cordova plugin add phonegap-plugin-push’
Error=> ERROR Error: Uncaught (in promise): plugin_not_installed

I use @ionic-native/push: 4.5.3 e phonegap-plugin-push: ^1.11.1
My platform is Android@6.3.0

ionic (Ionic CLI) : 4.0.1 (C:\Users\Dell\AppData\Roaming\npm\node_modules\ionic)
Ionic Framework : ionic-angular 3.9.2
@ionic/app-scripts : 3.1.8

cordova (Cordova CLI) : 8.0.0
Cordova Platforms : none

Android SDK Tools : 26.1.1
NodeJS : v7.10.1 (C:\Program Files\nodejs\node.exe)
npm : 4.2.0
OS : Windows 10

PS.: I found the problem! Is the phonegap-plugin-push, on v1.11.1 runs OK, but function createChannel do not works. When I update to v2.1.3 to run on Android@6.3.0, my project fail.

Help me please! ):
