ionic2 - why does ionic storage does not work outside a function -


i using ionic 2 storage. if keep storage code outside of function not work. kindly let me know.

constructor(public navctrl: navcontroller,     public settings: settings,     public formbuilder: formbuilder,     public navparams: navparams,     public translate: translateservice,     private storage : storage) {   }    this.settings.load().then(() => {       this.settingsready = true;       this.options = this.settings.allsettings;        this._buildform();     });      this.storage.set('nam','par');   }

the constructor special function of class responsible initializing variables of class. typescript defines constructor using constructor keyword. constructor function , hence can parameterized. until variable get's initialized remains undefined. so, can't in way , make no sense, constructor initialized before either can same operation within constructor or use life cycle event in ionic so.
