FlutterFlow and Filestack integration: Step-by-Step Guide 2024

Discover how to integrate FlutterFlow with Filestack in simple steps. Follow our clear, concise guide to seamlessly connect your mobile app with powerful file upload features.

What is Filestack?

Filestack is a digital tool that provides a file uploading and handling API for developers. It is designed to offer an effective way to add a customizable file uploader to any website, application or software. Filestack facilitates seamless integration with over 20 cloud services like Dropbox, Instagram, Google Drive, and more. It is capable of handling multiple file transformations including resizing, cropping, and format conversions, and involves secure delivery with built-in CDN capabilities.

How to integrate FlutterFlow with Filestack?

 

Step-by-Step Guide on How to Integrate FlutterFlow with Filestack

 

Step 1: Set Up Your Filestack Account

 
  • Sign Up: Visit Filestack's website and create an account if you don't have one already.
  • API Key: Once you log in, you will be provided with a unique API Key that will be used to authenticate your file uploads. Note this API Key as it will be needed in later steps.
 

Step 2: Create a New FlutterFlow Project or Open an Existing One

 
  • Log In: Go to FlutterFlow and log in to your account.
  • Project Dashboard: You can either create a new project or select an existing one from your dashboard.
  • Navigation: Navigate to the project editor where you'll be working on integrations.
 

Step 3: Add Dependency for HTTP Requests (Optional)

 

Although FlutterFlow manages dependencies, you might want to ensure you're capable of making HTTP requests.

  • HTTP Package: Make sure you include the HTTP package in your FlutterFlow project settings. If not, you can do this through the pubspec.yaml:
dependencies:
  http: ^0.13.3
 

Step 4: Set Up Custom Actions for Filestack in FlutterFlow

 

To interact with Filestack's API, you'll need to set up custom actions in FlutterFlow.

  • Custom Actions: On the FlutterFlow sidebar, navigate to the 'Custom Actions' tab.
  • New Action: Create a new custom action, name it UploadToFilestack.
  • HTTP Request: Define this custom action to make an HTTP POST request to Filestack's API endpoint
  • Endpoint: https://www.filestackapi.com/api/store/S3
  • Headers: Add headers such as Content-Type: multipart/form-data
  • Body: Include the file to be uploaded and the API Key.

Example Dart code for custom action:

import 'package:http/http.dart' as http;
import 'dart:convert';

Future uploadToFilestack(Uint8List fileBytes, String fileName) async {
  try {
    var request = http.MultipartRequest('POST', Uri.parse('https://www.filestackapi.com/api/store/S3'));
    request.fields['key'] = 'YOUR_FILESTACK_API\_KEY';
    request.files.add(http.MultipartFile.fromBytes('fileUpload', fileBytes, filename: fileName));
  
    var response = await request.send();
    if (response.statusCode == 200) {
      print('Uploaded successfully!');
    } else {
      print('Failed to upload');
    }
  } catch (e) {
    print('Error: $e');
  }
}
 

Step 5: Configure UI Components

 

To integrate the file upload feature into your app's UI, you'll need to configure UI components in FlutterFlow.

  • File Picker: Add a button or any interactive element to trigger the file picker dialog.
  • UI Action: Attach the file picker action to this button which upon file selection, calls the uploadToFilestack custom action.

Steps to do this:

  1. Drag and drop a button widget.
  2. Go to Button Properties → On Tap → Add Action → Custom Actions → UploadToFilestack.
  3. Ensure you pass necessary parameters (file data and file name) correctly.
 

Step 6: Test the Integration

 
  • Emulator/Device: Run your FlutterFlow project on an emulator or a physical device.
  • Select File: Interact with the UI to select a file and upload.
  • Verification: Verify the upload process by checking the response and validating the file in your Filestack dashboard.
 

Step 7: Debug and Optimize

 
  • Console Logs: Use debug prints and console logs to monitor the file upload process.
  • Error Handling: Implement error handling within your custom action to manage failed uploads gracefully.
  • Optimization: Optimize UI/UX based on feedback to ensure a smooth user experience.

By following these steps diligently, you can successfully integrate Filestack with your FlutterFlow project, thereby enhancing your app's file management capabilities.

 

FlutterFlow and Filestack integration usecase

Scenario:

An online education platform wants to enhance its user experience by providing a seamless method for instructors to upload and manage their teaching materials directly from their mobile app or web dashboard. They decide to use FlutterFlow to create these interfaces while leveraging Filestack for secure and efficient file handling.

Solution: Integrating FlutterFlow with Filestack

Instructor Dashboard Creation:

  • The platform uses FlutterFlow to design an intuitive instructor dashboard within their mobile app and web version. This dashboard includes functionalities for uploading, organizing, and managing teaching materials like PDFs, videos, and images.

Setting Up the Integration:

  • The development team installs the Filestack API integration within FlutterFlow, configuring it with their Filestack API key.
  • They set up workflows in FlutterFlow to trigger Filestack actions, such as file upload, when an instructor interacts with the dashboard.

File Upload Workflow:

  • When an instructor selects a file to upload, the workflow is triggered.
  • The selected file is uploaded directly to Filestack using the configured Filestack API action.
  • Filestack returns a URL for the uploaded file, which is stored in the platform’s database for future access and management.

Material Management:

  • Instructors can view, edit, or delete their uploaded files from the dashboard. These actions trigger additional workflows managed by Filestack to ensure files are updated or removed securely and efficiently.

SEO and Image Transformation:

  • The platform uses Filestack's built-in image transformation capabilities to optimize images for different devices and contexts (e.g., thumbnails, full-size views) using real-time URL-based transformations.
  • This ensures fast loading times and a consistent user experience across all devices.

Secure File Handling:

  • Filestack’s robust security features, like file encryption and content protection, ensure that sensitive teaching materials are securely stored and only accessible to authorized users.
  • The platform can configure and enforce security policies through the Filestack API to comply with privacy regulations and protect intellectual property.

Monitoring and Analytics:

  • The integration allows for detailed tracking of file usage and interactions within the instructor dashboard.
  • The platform can monitor the volume of uploads, downloads, and other interactions, gaining insights into how often and in what context files are accessed.

Benefits:

  • Enhanced User Experience: Instructors can easily upload, manage, and retrieve their teaching materials, leading to higher satisfaction and engagement.
  • Efficiency: Automating file handling processes saves time and reduces the complexity for instructors and the development team.
  • Centralized Data: All teaching materials are securely handled and stored in one place, simplifying management and retrieval.
  • Security: Filestack’s advanced security features ensure that all materials are protected against unauthorized access and data breaches.
  • Scalability: The platform can handle an increasing number of instructors and teaching materials without compromising performance or security.

Conclusion:

By integrating FlutterFlow with Filestack, the online education platform significantly enhances the experience for instructors managing their teaching materials, ensuring a seamless, secure, and efficient process that supports the platform’s growth and user satisfaction.
