I am facing cannot read socialsharing

[Abdulzabeer]

var cordova = window.cordova; shareVia(type?: string, message?: string, subject?: string, file?: any) { return new Promise((resolve, reject) => { var options = { message: '', subject: '', files: [file], } var onSuccess = function (result) { resolve(result) }

var onError = function (msg) {
  reject(msg)
}
if (cordova.plugins.socialsharing) {
  document.addEventListener('deviceready', ()=>{
    cordova.plugins.socialsharing.shareWithOptions(options, onSuccess, onError);
  }, false); 

} else {
  reject('Plugin not available');
}

}); }
