A simple Flutter app that can wake devices with WOL

simple_wol

A Flutter application where you can add WOL devices and wake them up over the LAN. This was done as part of an exercise for school.

What did I learn here?

• how to use basic JSON operations in Dart
• make a dialog in Flutter (AlertDialog)
• build a form and add validation + input formatting (making everything uppercase or only valid characters from a RegEx) (AddForm)
• manage basic state (StatefulWidget)
• save data on the device with the shared_preferences module
• use external modules in general (ex: wake_on_lan)
• add an icon to a Flutter app with flutter_launcher_icons

What each file does

lib/main.dart

The entrypoint for the application. It manages the list state of the WOLItems and displays the AlertDialog used for adding devices.

lib/shared.dart

This contains helper functions for saving and getting data from SharedPreferences.

lib/util.dart

This contains helper widgets (in this case only the AddForm widget). The AddForm widget is the content of the AlertDialog that gets displayed when trying to add a device.

lib/wol.dart

Contains the WOLItem class that is used for saving the data of a device.
