Firebase Plugin does not exist

Hey’ !

Trying to use firebase to push notification i follow this tutorial :

But when i launch my app i get theses errors :

2018-06-12 12:26:06.515175+0200 StaffinV2[5605:873546] CDVPlugin class FirebasePlugin (pluginName: FirebasePlugin) does not exist.
2018-06-12 12:26:06.515221+0200 StaffinV2[5605:873546] ERROR: Plugin 'FirebasePlugin' not found, or is not a CDVPlugin. Check your plugin mapping in config.xml.

In my config file i have this line : <plugin name="cordova-plugin-firebase" spec="^1.0.5" />

I don’t know i am doing wrong :confused:

Did you find any solution that was the time? please tell me having the same issue.
