ionic3 plugin and platform errors - ionic-framework

Question

I am using ionic CLI version 3.0.0-beta.5
When I am trying to install native plugins, I am getting these errors.
for example, installing social-sharing plugin
ionic plugin add cordova-plugin-x-socialsharing
and the error is
[ERROR] Unknown plugin: #ionic/cli-plugin-.
same error while adding platforms also..
C:\Users\varun\Desktop\apps\app>ionic platform add android
The platform command is no longer available. To find out more about the equivalent please run:
ionic cordova:platform --help
C:\Users\varun\Desktop\apps\app>ionic cordova:platform --help
[ERROR] Unable to find command: cordova:platform. It is possible that you are trying to get help on a project based command and you are not in a project directory.
Has anyone faced this problem? I am not getting enough information on official blog.

Answer 1

To fix "The platform command is no longer available" issue on Ionic3 beta 7 I tried the following:
ionic cordova:platform add android
However, it only worked for newly started projects so need to update ionic-scripts in your project.

Answer 2

Use this instead
cordova plugin add https://github.com/EddyVerbruggen/SocialSharing-PhoneGap-Plugin.git
The repo name cordova-plugin-x-socialsharing is changed/missing
so, we can directly add plugin from plugin git repo.
shareWithOptions(option, successcallback, errorcallback);
Usage :
window.plugins.socialsharing.shareWithOptions( {
message: 'share this',
subject: 'the subject',
files: ['', ''],
url: 'https://www.gooogle.com',
chooserTitle: 'Pick an app'
},
function(success){
console.log(success);
},
function(err){
console.log(err);});
