Institutional Repository UIN Sunan Kalijaga YogyakartaPENGEMBANGAN LIBRARY FLUTTER UNTUK OTOMATISASI INTEGRASI API BERBASIS SWAGGER MENGGUNAKAN METODE EXTREME PROGRAMMINGNIM.: 22106050034Rifky Tyo Ramadhani SantosoauthorModern mobile application development frequently utilizes Application Programming Interfaces (APIs) as a primary data source. However, the process of API integration in Flutter is still commonly performed manually, resulting in repetitive code writing, increased potential for errors, and a lack of consistency in code structure. This study aims to develop and evaluate a Flutter library called Swagen, which is capable of automating API integration based on Swagger/OpenAPI through a code generation approach. The development method used is Extreme Programming, while testing is conducted using Black Box Testing and system evaluation is carried out using the Technology Acceptance Model (TAM). The results show that all features of Swagen function according to the specified requirements. Furthermore, the TAM evaluation results indicate a good to very good level of user acceptance, with an average score of 4.13 (very good) for Perceived Ease of Use, 4.35 (very good) for Perceived Usefulness, 4.23 (very good) for Attitude Toward Using, 4.28 (very good) for Behavioral Intention to Use, and 3.67 (good) for Actual Use. Thus, Swagen is able to improve the efficiency of Flutter application development, reduce manual work, and produce a more consistent code structure in accordance with Clean Architecture principles.004 Pemrosesan Data, Ilmu Komputer, Teknik Informatika2026-04-22UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SAINS DAN TEKNOLOGIThesis
