My current challenge involves sending data from one controller to another within an Ionic application. Despite creating a service for this purpose, I am still unable to share the data successfully. The send() function in MainCtrl is meant to pass the data to SubCtrl, but something seems to be missing. Any insights on what I may be overlooking to achieve this task?
var app = angular.module('testapp', []);
