Invite Link & QR Sharing

Referral programs are among the most cost-effective member acquisition channels for volunteer organizations, leveraging existing trust networks rather than paid outreach. HLF explicitly identified vervefunksjonalitet as a strategic organizational need, framing the mobile app as a marketed member benefit - a recruitment tool in itself. QR code support enables face-to-face recruitment at workshops and events, matching the peer mentor working context. Personalized links make each peer mentor an active ambassador, increasing organizational reach without additional marketing spend. Attribution data also feeds the gamification layer, making recruiting impact visible and motivating continued engagement among peer mentors.

Flutter implementation uses deep links generated via Firebase Dynamic Links or a lightweight custom deep-link service, with QR code rendering handled client-side by the qr_flutter package. The backend creates a unique referral token per request, stored in the referral_links table with the referring user ID and creation timestamp. The platform share sheet is triggered via the share_plus package, requiring no custom share UI. On new user registration the onboarding flow captures the referral token from the incoming deep link and posts it to the backend, which writes a referral_events row for attribution. Token expiry and single-use enforcement should be configurable per organization to align with varying recruitment policies.
