Requesting camera permission in Flutter (permission_handler)

In the profile settings after login, we can add a profile picture. To request permission to access the camera, the process is very similar to requesting access to the user's contacts.

We create a function to check and request permission, if needed:

void _checkPermissions() async { PermissionStatus status = await PermissionHandler()        .checkPermissionStatus(PermissionGroup.camera); // 1    if (status != PermissionStatus.granted) { // 2    await PermissionHandler().requestPermissions([PermissionGroup.camera]);     // 3    }  }

The method is very similar to the check completed in the contact import example:

1. We get the status of the camera permission from the API.
2. We test whether the status is different ...
