How do you handle different permission states (like denied or permanently denied) for accessing device features in Flutter?

In Flutter, handling different permission states involves using conditional statements based on the permissionStatus. Developers can check whether a permission is granted, denied, or permanently denied and implement appropriate actions. This typically involves requesting permissions, displaying custom dialogs, or directing users to device settings. Understanding how to manage permissions gracefully enhances the user experience and ensures the smooth functioning of Flutter apps accessing device features.
