Everything You Need To Know About Flutter App Permissions and How To Handle Permissions
Before diving into the core issue, let’s first discuss the importance of permissions. We have a package known as “permission_handler”, which offers a cross-platform (iOS and Android) API for requesting permissions and checking their status. You can refer to the documentation for this package at https://pub.dev/packages/permission_handler.
However, it’s essential to note that there is no inherent issue with this package itself. Our concern lies elsewhere, and we will explore it in detail shortly. Here, we’ll discuss how to handle flutter app permissions.
Consider a scenario in which we request specific permission from the “permission_handler” package. When the app requests permission, it prompts the user to grant or deny access.
What if we want to enforce a strict policy where, if the user denies permission, they cannot use the app’s functionalities until they grant the necessary permission?
For example, the camera permission. If the user denies Camera permission initially, we’ve implemented code to display a dialog box. This dialog box contains a single button that directs the user to the app’s settings which allows them to grant the required permission. After returning to the app following the permission grant, this is where the issue arises.
The problem is that even after the user grants permission, the status does not update accordingly. The dialog box remains visible, even though the user has provided the necessary permission.
This situation is undesirable for developers who want their apps to function seamlessly. Let’s check how to address and resolve this particular challenge.

Let’s understand with code.
As a prerequisite, we need to add a package in pubspec.yaml file.
