About this Gig
Connect your existing Flutter screens to documented REST APIs with clear loading, empty and error states.
BASIC: Up to 2 JSON endpoints connected to up to 2 existing screens.
STANDARD: Up to 5 endpoints and 3 existing screens, including documented token authentication and pagination for one list.
PREMIUM: Up to 10 endpoints and 5 existing screens, including Standard features, a documented token-refresh flow and one file-upload flow. Auth and upload requests count toward the endpoint limit.
You receive Dart models, reusable request code, changed source, setup notes and checks for agreed success and failure cases. Each package covers one Android OR iOS target.
The backend and UI must already work. New backend development, payment checkout, AI features, new screen design and store submission are outside these packages. Provider fees are yours.
Send your API documentation or Postman collection, runnable source and target platform on Fiverr before ordering so we can confirm scope and acceptance checks.

FAQ
What counts as an endpoint?
One endpoint is one HTTP method plus route and one agreed response/use case. GET and POST on the same path count separately. Login, token refresh and upload requests count within the package limit. Share the exact inventory before ordering.
Do you build the backend or design new screens?
No. These packages connect documented, functioning REST endpoints to existing Flutter screens. Backend development, new UI design, database schema work and fixing the provider's service require separate scope.
Can you include login, pagination and uploads?
Standard includes an existing token-auth flow and pagination for one list. Premium adds a documented refresh-token flow and one file upload to an existing endpoint. These depend on working backend support and count within the endpoint limit.
Are payment gateways or AI integrations included?
No. Payment checkout and AI provider features require different validation and scope. This gig focuses on ordinary documented application data APIs. Please describe those requests separately on Fiverr.
Which Flutter packages and architecture will you use?
I review the project's current HTTP client, models and state management before quoting. I normally work within the existing architecture. A state-management migration, offline sync system or broad refactor is a separate project.
What platforms and test evidence do I receive?
One agreed Android or iOS target is included. I provide changed source, setup notes and checks for agreed successful, unauthorized and network/error cases where applicable. Extra OS targets and signed store releases need separate scope.
What does a revision cover?
It covers adjustments to the agreed endpoints, mappings and existing-screen behavior. New routes, changed provider contracts, new UI or backend features require a new quote. API usage and subscription charges are paid through your account.
