AngularJS error: [ng:areq] The specified argument '...' is not a function and is instead undefined

Starting my project with Angular version 1.5 and above.

Below is the code for my controller:

'use strict';

(function(){

class FlamingoController {
    constructor($http) {
        this.$http = $http;
        this.flamingo = [];
    }

    $onInit() {
        this.$http.get('/api/flamingo')
            .then(response => {
                this.flamingo = response.data;
            })
    }
}

angular.module('wildroseApp')
  .component('flamingo', {
    templateUrl: 'app/flamingo/flamingo.html',
    controller: FlamingoController,
  });

})();

When I attempt to add my controller in the view like this:

<div class="container" ng-controller="FlamingoController as ctrl">

I encounter the following error:

Error: [ng:areq] Argument 'FlamingoController' is not a function, got undefined

It seems like you may have overlooked including the ng-app or adding the necessary file to the header. Have you confirmed in the network if the controller has been successfully loaded?

Personally, I have never included it in an angular project so I would suggest removing it.
