Flutter+Stripe
Stack IntegrationFlutter + Stripe Payments Integration
Adding Stripe to a Flutter app requires a backend to create PaymentIntents — the secret key never touches the client. The `flutter_stripe` package handles the native payment sheet.
Use Cases
- Native payment sheet (Apple Pay, Google Pay, card)
- Subscription billing with Stripe + Firebase/Supabase
- One-time purchases and in-app payments
- Payment status synced to backend via webhooks
Implementation
Flow: Flutter calls your backend → backend creates PaymentIntent with Stripe secret key → returns `client_secret` → Flutter presents payment sheet. Never pass the Stripe secret key to the Flutter app. Use `flutter_stripe` package for the native payment sheet UI.
