Try below code with a package permission_handler to manage permissions.

    @override
    void initState() {
      super.initState();
      checkPermission();
    }
    
    Future<void> getImage() async {
      PermissionStatus status = await Permission.photos.status;
      if (status.isGranted) {
        // Proceed to pick an image
      } else {
        await requestPermission();
      }
    }

Check the current status of the permission with below method.

    Future<void> checkPermission() async {
      PermissionStatus status = await Permission.photos.status;
    
      if (status.isDenied) {
        // Permission is denied, show a dialog or message to the user
      } else if (status.isGranted) {
        // Permission is granted, proceed with accessing images
      }
    }

If permission is denied,show a dialog explaining why the permission is necessary and how to enable it.

    void showPermissionDialog(BuildContext context) {
      showDialog(
        context: context,
        builder: (BuildContext context) {
          return AlertDialog(
            title: Text('Permission Required'),
            content: Text('This app needs permission to access your photos. Please enable it in settings.'),
            actions: <Widget>[
              TextButton(
                child: Text('Open Settings'),
                onPressed: () {
                  openAppSettings();
                },
              ),
              TextButton(
                child: Text('Cancel'),
                onPressed: () {
                  Navigator.of(context).pop();
                },
              ),
            ],
          );
        },
      );

If user initially denies the permission but has not permanently denied it, you can request the permission again with below method.

    Future<void> requestPermission() async {
      PermissionStatus status = await Permission.photos.request();
    
      if (status.isGranted) {
        // Permission granted, proceed with accessing images
      } else if (status.isDenied) {
        // Permission still denied, show a dialog
        showPermissionDialog(context);
      } else if (status.isPermanentlyDenied) {
        // Permission is permanently denied
        showPermissionDialog(context);
      }
    }
