Services in angularJS not working in controller

[Stanislav]

Hi, Everybody. I Have a  stupid problem with a services. Why they always undefined? I Use one of latest version of angularJS 1.7.6.

var app = angular.module("appTestApp", []);
app.service('Calculator', function () {
    this.square = function () {
        console.log("This is service")
    };
});

app.run(function ($transitions, $state) {
    $transitions.onStart({}, function(transition, $state, toState, $rootScope, Calculator){
        

        console.log(Calculator)

        Calculator.square()

    });
});

And I have such result in console.
