FAQ
Why do you use Flutter for app development?
Flutter allows me to build native-like, high-performance apps for both iOS and Android from a single codebase. This significantly reduces development time and costs for you, while delivering a smooth and beautiful user experience without screen freezing.
What do I need to provide to start the API integration?
Please provide your API documentation (like a Postman collection, Swagger link, or PDF), API keys or test credentials if authentication is required, and your UI/UX designs (Figma/Adobe XD) if you have them.
My app requires more than 10 API endpoints and screens. Can you handle it?
Yes, absolutely! The packages listed are standard options. Please send me a message with your complete project details, and I will create a custom offer tailored to your specific app requirements.
