📦☁️ iCloud_Storage_Sync Plugin

Seamless iCloud integration for your Flutter iOS apps!

🌟 Introduction

iCloud_Storage_Sync simplifies iCloud storage integration, bringing powerful cloud capabilities to your Flutter iOS apps:

🔄 Effortless backup and sync of app data

📱💻 Consistent user experience across all devices

🔒 Secure storage and retrieval of important information

☁️ Seamless integration with the iCloud ecosystem

✨ Features

Feature	Description
📂	Get iCloud files
⬆️	Upload files to iCloud
✏️	Rename iCloud files
🗑️	Delete iCloud files
↔️	Move iCloud files
🔍	Filter by path prefix
⏱️	Timeout support

Advanced Features:

• 🔍 Path Filtering - Query specific subdirectories instead of entire container for better performance
• ⏱️ Timeout Support - Set time limits on metadata queries to prevent indefinite hangs
• 📊 Progress Tracking - Monitor upload/download progress with callbacks
• 🔄 Stream Updates - Receive live updates as files change in iCloud

🚀 Getting Started

1. 🛠️ Installation

Add this to your pubspec.yaml:

dependencies:
  icloud_storage_sync: ^1.0.0

2. ⚙️ Install the Plugin

Run:

flutter pub get

3. 🔧 Configure Your iCloud Container ID

Update your iCloud Container ID in the example app:

In example/lib/controller/icloud_plugin_controller.dart:

final iCloudContainerId = 'iCloud.com.yourcompany.appname'; // Replace with your container ID

In example/ios/Runner/Info.plist:

<key>iCloud.com.yourcompany.appname</key>  <!-- Replace with your container ID -->

In example/ios/Runner/Runner.entitlements and RunnerDebug.entitlements:

<string>iCloud.com.yourcompany.appname</string>  <!-- Replace with your container ID -->

ℹ️ Note: Your iCloud Container ID should match the format: iCloud.<your-team-id>.<your-bundle-id>

4. 💻 Usage

Import in your Dart code:

import 'package:icloud_storage_sync/icloud_storage_sync.dart';

📋 Prerequisites

Before diving in, make sure you have:

☑️ An Apple Developer account

☑️ App ID and iCloud Container ID

☑️ iCloud capability enabled and assigned

☑️ iCloud capability configured in Xcode

🔍 See How to set up iCloud Container for step-by-step instructions.

🧰 API Examples

📥 Getting iCloud Files

Future<List<CloudFiles>> getCloudFiles({required String containerId}) async {
  return await icloudSyncPlugin.getCloudFiles(containerId: containerId);
}

📂 Gathering Files with Path Filtering & Timeout

// Gather files with optional path prefix filtering
Future<List<ICloudFile>> gatherFilesFromSubdirectory({
  required String containerId,
  required String pathPrefix,
}) async {
  return await icloudSyncPlugin.gather(
    containerId: containerId,
    relativePathPrefix: pathPrefix, // e.g., 'Documents/', 'Projects/MyApp/'
  );
}

// Gather files with timeout to prevent indefinite hangs
Future<List<ICloudFile>> gatherFilesWithTimeout({
  required String containerId,
  required Duration timeout,
}) async {
  try {
    return await icloudSyncPlugin.gather(
      containerId: containerId,
      timeout: timeout, // e.g., Duration(seconds: 30)
    );
  } on PlatformException catch (e) {
    if (e.code == 'METADATA_QUERY_TIMEOUT') {
      debugPrint('iCloud query timed out');
    }
    return [];
  }
}

// Combine both features for optimal performance
Future<List<ICloudFile>> gatherFilesOptimized({
  required String containerId,
  required String pathPrefix,
}) async {
  return await icloudSyncPlugin.gather(
    containerId: containerId,
    relativePathPrefix: pathPrefix,
    timeout: Duration(seconds: 30),
  );
}

Features:

• 📂 relativePathPrefix - Filter to specific subdirectory for faster queries
• ⏱️ timeout - Set time limit to prevent indefinite hangs
• 🔄 Both parameters are optional and backwards compatible

📤 Uploading Files to iCloud

Future<void> upload({
  required String containerId,
  required String filePath,
  String? destinationRelativePath,
  StreamHandler<double>? onProgress,
}) async {
  await icloudSyncPlugin.upload(
    containerId: containerId,
    filePath: filePath,
    destinationRelativePath: destinationRelativePath,
    onProgress: onProgress,
  );
}

🏷️ Renaming iCloud Files

Future<void> rename({
  required String containerId,
  required String relativePath,
  required String newName,
}) async {
  await icloudSyncPlugin.rename(
    containerId: containerId,
    relativePath: relativePath,
    newName: newName,
  );
}

🗑️ Deleting iCloud Files

Future<void> delete({
  required String containerId,
  required String relativePath,
  required bool isDirectory
}) async {
  await icloudSyncPlugin.delete(
    containerId: containerId,
    relativePath: relativePath,
    isDirectory: isDirectory
  );
}

🔄 Replace iCloud Files

Future replaceFile({
  required String updatedFilePath,
  required String relativePath
  }) async {
    await icloudSyncPlugin.replace(
      containerId: iCloudContainerId,
      updatedFilePath: updatedFilePath,
      relativePath: relativePath,
    );
}

🔀 Moving iCloud Files

Future<void> move({
  required String containerId,
  required String fromRelativePath,
  required String toRelativePath,
}) async {
  await IcloudSyncPlatform.instance.move(
    containerId: containerId,
    fromRelativePath: fromRelativePath,
    toRelativePath: toRelativePath,
  );
}
