       this.googlePlus.login({
          'webClientId': '#####', //reverse client id

Answer 1

its occurred mismatch about your SHA-1 key mismatch with app id or your release or debug key

ionic cordova plugin add cordova-plugin-googleplus --variable REVERSED_CLIENT_ID=279073034910-0000000000000000000.apps.googleusercontent.com

npm install --save @ionic-native/google-plus@4

Note: in ionic youcan find packagename config.xml top of it widget id="com.your.id"
