environment: 'production'

[ValenOnish]

my config.json file with multiple environments:
{
  "local": {
    "EnvironmentConfig": {
      "api": "http://localhost/"
    }
  },
  "production": {
    "EnvironmentConfig": {
      "api": "https://api.production.com/"
    }
  }
}
Usage of the plugin:
gulpNgConfig('myApp.config', {
  environment: 'production'
})
Expected output:
angular.module('myApp.config', [])
.constant('EnvironmentConfig', {"api": "https://api.production.com/"});

But my output configFile.js:
angular.module("todoApp.config", [])
.constant("local", {"EnvironmentConfig":{"api":"http://localhost/"}})
.constant("production", {"EnvironmentConfig":{"api":"https://api.production.com/"}});

What's wrong?
