Question

What\'s the best programming practice to

create a constant class in Flutter

to keep all the application constants for easy referenc

Answer 1

For all constants, just create constants.dart file under lib folder or lib/util folder, then keep all constant variables as follows :

 const SUCCESS_MESSAGE=" You will be contacted by us very soon.";

 // Api related 
 const apiBaseURL = "https://baseurl.com";
    
 const userLoginApi = "login";
 const userSignupApi = "signup";
    
 // Shared Preference keys 
 const kDeviceName = "device_name";
 const kDeviceUDID = "device_id";

 // Asset Constants
 const navBarLogoImage = "assets/images/home_images/sample.png
   

then import constants.dart file in required class and use it directly.
