How to pass data from one widget to another widget?

We can use $emit, $broadcast and $on to send and recieve the data.

– Example by using $broadcast

Include below code in client controller on source widget to send data.
$rootScope.$broadcast('dataEvent', data);

Include below code in client controller on target widget to recieve data.
$scope.$on('dataEvent', function (event, data) {
console.log(data); // 'recieved data'
});

– Example by using $emit

Include below code in client controller on source widget to send data.
$rootScope.$emit('dataEvent', id);

Include below code in client controller on target widget to recieve data.
$scope.$on('dataEvent', function (event, data) {
console.log(data); // 'recieved data'
});
