About this gig
Need reliable REST API or Firebase integration for your Flutter application? I will connect your app to backend services using clean, maintainable, and scalable Flutter code.
With 6 years of professional Flutter experience, I can help with:
REST API integration using Dio, HTTP, or Retrofit
Firebase Authentication, Firestore, Storage, and FCM
JSON parsing and model creation
Login, registration, and token-based authentication
GET, POST, PUT, PATCH, and DELETE requests
Loading, success, empty, and error states
BLoC, Cubit, GetX, Riverpod, or Provider integration
Pagination, search, filtering, and file uploads
Local caching and secure token storage
Android and iOS support
One endpoint represents one API operation, such as login, fetching products, creating an order, or updating a profile. Payment gateways, real-time streaming, WebSockets, and third-party SDKs require a custom offer. Please contact me before ordering if your requirements are complex or unclear.

FAQ
What counts as one API endpoint?
One endpoint means one API operation, such as login, registration, fetching a product list, creating an order, or updating a profile.
Can you integrate both REST APIs and Firebase?
Yes. I can integrate REST APIs and Firebase services. The required package depends on the number and complexity of the integrations.
Do you develop the backend API?
This service primarily covers integration with an existing API or Firebase project. Node.js and Express.js backend development can be provided through a custom offer.
What must I provide before work begins?
Please provide the Flutter source code, API documentation or Postman collection, required endpoints, sample responses, and temporary test credentials when needed.
Are payment gateways or real-time features included?
Payment gateways, WebSockets, live streaming, chat, Agora, and other complex third-party integrations are not included by default and require a custom offer.
