device_manager 0.0.7

Manager for hardware devices(USB, Serial. etc...) for Flutter Windows Desktop applications.

Device Manager for Flutter

device_manager is a simple transmitter for the WM_DEVICECHANGE message. In other words, your Flutter Win32 App will be notified anytime there is a new hardware device connected to the computer.

Supported platforms:

• Windows
• Android

Usage

To use this package, add device_manager as a dependency in your pubspec.yaml file.

Now go to lib\main.dart and add this code in the main function right after runApp(MyApp()); :

DeviceManager().addListener(() {
    var event = DeviceManager().lastEvent;
    if (event != null) {
        if (event.eventType == EventType.add) {
          scaffoldKey.currentState!.showSnackBar(
          const SnackBar(content: Text('New device detected!')));
        } else if (event.eventType == EventType.remove) {
          scaffoldKey.currentState!.showSnackBar(const SnackBar(content: Text('Device removed!')));
        }
    }
});

This listener will be called anytime a device had been connected or disconnected.
