I need a Flutter developer who knows the ABDM FHIR standards inside out to turn my concept for a medical-records exchange app into a polished, production-ready build that runs smoothly on both iOS and Android. The core of the project is enabling secure, standards-compliant sharing of patient data. In practice that means: • Record Viewing – pull and render FHIR resources clearly, handling complex clinical data types without lag. • Record Updating – let authorised users add or amend data while maintaining provenance and audit trails. • Record Sharing – generate and transmit consent-based bundles so records flow seamlessly between ABDM-registered providers. • Consent Management. • Facility Discovery • Add Patient Profile • Other ABDM Functionalities to be integrated, refer this https://sandbox.abdm.gov.in/sandbox/v3/new-documentation?doc=BuildingPHRApp I will supply UI wireframes, ABDM sandbox access and an API key. You will wire up the Flutter front end, integrate with the ABDM gateway, test against the sandbox, then package the app for release on both app stores. Acceptance criteria will be met when: • All three features work end-to-end in the sandbox with no validation errors. • The build passes Android (API 23+) and iOS (14+) review guidelines. • You hand over clean, well-commented Dart code and a short deployment read-me. If you have shipped Flutter apps that talk FHIR before, especially within India’s ABDM ecosystem, I’d love to see your work and move ahead quickly.
