The Flutter Postal Code App is a simple yet comprehensive application that displays postal codes, post offices, and districts in an easy-to-navigate format. Designed for anyone needing postal information, this app uses a Table widget to present district, post office, and postal code details in three columns. Each data point is clickable, triggering a popup that provides further information via the Flutter toast package. A Drawer widget in the app bar offers quick navigation to other pages, making it easy for users to explore various sections. This project is ideal for students and developers eager to learn Flutter widgets, list structures, and navigation features.
