Litbang TNI AU App

Litbang TNI AU App is an internal Flutter application built to support document distribution, follow-up actions, approvals, and cross-role tracking within the Litbang TNI AU environment.

Quick Summary

Litbang TNI AU App is an internal Flutter application built to support document distribution, follow-up actions, approvals, and cross-role tracking within the Litbang TNI AU environment.

Problems Solved

Internal document distribution was still slow because many steps were handled manually.

Document status was difficult to monitor end to end.

Cross-role coordination for reading, approving, and following up on documents was not efficient.

Files and response history were scattered, increasing the risk of miscommunication.

Key Features

Authentication and session handling with secure storage.

Document lists with categories such as TANDA_TANGAN, INFORMASI, and TINDAK_LANJUT.

Document detail views containing files, involved parties, and process history.

Role-based workflows for accept, sign, response, forward, and add people actions.

Direct file download and open flow from the device.

Multi-environment setup for development, staging, and production.

Project Architecture

This project uses a feature-based modular approach. The main layers are separated into feature areas, shared utilities, resources, and app configuration, making business logic, dependencies, storage, and UI components easier to maintain and extend. This structure helps the project stay scalable as the number of modules, workflows, and roles grows.
