i am new in ionic and started from youtube tutorials , i created a crud in ionic using PHP, my sql in success login i redirect to home page and by using home.page.ts i can get storage data in home.page.html, but i am not able to pass user storage data in side menu to show user name in side menu, i tried in app. component. ts to get storage data and pass to side menu which html is in app. component. html but its not showing on first login but after login when i refresh it shows name that’s because it is added storage else condition in app. component. ts i even added that method in after ready but still no luck i need help on this pls.
