Implementation of Flutter Framework in Frontend Development of Android-Based Audio Scheduling Application
Abstract
Abstrak — Flutter is an open-source framework developed
by Google to support cross-platform mobile application
interface development. This study implements Flutter in the
frontend development of an Android-based audio scheduling
application designed to improve information delivery in early
childhood education environments. The case study was
conducted at TK IT Little Moslem, where manual bells and
speakers were still used, resulting in inefficient communication.
The developed application, named SoundNest, allows teachers
to schedule audio playback (bells, music, and Qur’anic
recitations), control volume, and deliver announcements
through a user-friendly interface. Flutter was used to build
interactive layouts using widgets such as ListView, Switch, and
TabBar, while Firebase Realtime Database handled real-time
data storage and synchronization. Testing was conducted using
white-box, black-box, and User Acceptance Testing (UAT)
methods, with 13 teachers participating as respondents. The
UAT yielded an average score of 56.69 out of 60, and the
Cronbach’s Alpha reliability score was 0.947, indicating
excellent internal consistency. The results confirm that the
application is efficient, responsive, and easy to use. Thus, Flutter
proves effective for building dynamic and educational Android
interfaces and serves as a functional solution to improve
communication at TK IT Little Moslem.
Keywords — flutter, frontend, android, audio scheduling,
firebase, user interface.
