🚀 Identity Verification in FlutterFlow using uqudo SDK

🚀 Identity Verification in FlutterFlow using uqudo SDK

May 1, 20263 min read


🔍 Overview
In modern applications, secure and seamless user onboarding is critical — especially when identity verification (KYC) is involved.

In this article, I’ll walk through how we integrated the uqudo SDK Flutter plugin into a FlutterFlow application using Custom Actions to enable a robust identity verification flow.

This solution leverages uqudo’s official Android and iOS SDKs to deliver a secure, scalable, and efficient KYC experience — particularly optimized for users across the Middle East & Africa.

🎯 Objective
The goal was to implement a reliable identity verification system in FlutterFlow that:

  • Accelerates user onboarding
  • Reduces manual verification efforts
  • Seamlessly integrates into a no-code / low-code workflow
  • Maintains high security and accuracy

🛠 Technology Stack

  • FlutterFlow
  • Custom Actions (Flutter code)
  • uqudo SDK Flutter Plugin
  • Android & iOS Native SDKs
  • Device Camera (Front Camera)

🧩 Architecture & Implementation Approach
To integrate uqudo into FlutterFlow, we followed a hybrid approach:

  • The uqudo Flutter plugin was added to the FlutterFlow project

  • Custom Actions were used to bridge FlutterFlow UI with SDK functionality

  • Platform-specific logic was handled in:

  • android/ (native implementation)

  • ios/ (native implementation)
    This approach allowed us to:

  • Use advanced native SDK features

  • Keep FlutterFlow UI clean and manageable

  • Maintain flexibility for future enhancements

🔄 Verification Flow
1️⃣ Identity Document Scanning
We implemented document scanning for:

  • Aadhaar Card
  • PAN Card Using uqudo’s document verification capabilities, the app extracts and validates identity data efficiently.

2️⃣ Face Capture & Biometric Verification

  • The device’s front camera is used to capture the user’s face
  • Face matching is performed against the scanned document

This ensures:

  • Authenticity
  • Fraud prevention
  • Real-time verification

3️⃣ Verification Result Handling
Clear outcomes are displayed directly in the UI:

  • ✅ Face matched successfully
  • ❌ Face mismatch detected This improves transparency and user trust during onboarding.

4️⃣ Error Handling & User Feedback
Robust error handling was implemented using Custom Actions to manage:

  • Invalid document scans
  • Face mismatch scenarios
  • Camera permission issues
  • SDK-related errors Providing clear feedback significantly improved the user experience.

Outcome & Impact
Successfully implemented a production-ready KYC flow within FlutterFlow
Reduced onboarding friction with automation
Enabled seamless integration of native SDKs in a low-code environment
Improved user trust with real-time verification feedback

🚀 Key Learnings
FlutterFlow Custom Actions are powerful for integrating complex SDKs
Combining low-code UI with custom Flutter logic offers both speed and flexibility
Native SDK integration is achievable without compromising maintainability
Proper error handling is critical for user trust and retention

🔗 Conclusion
Integrating the uqudo SDK in FlutterFlow using Custom Actions proved to be an effective approach for building a secure and scalable identity verification system.

This method bridges the gap between low-code development and advanced native capabilities, enabling faster delivery without sacrificing control or performance.

Final Thoughts
If you’re building a FlutterFlow app that requires KYC, identity verification, or onboarding automation, this approach can significantly reduce development complexity while ensuring a high-quality user experience.
