                    try {

                      await appwriteService.init();

                      // Create a signed URL that includes authentication
                      final result = await appwriteService.storage.getFilePreview(
                        bucketId: "patient_profile_images",
                        fileId: "67d96a039e2087bf7399",
                      );

                      debugPrint('🌐 AppwriteService: Result: $result');

                    } catch (e) {
                      debugPrint('❌ AppwriteService $e');
                    }
                  }, child: Text("Get Image preview ")),```
