Linux implementation of gamepads, a Flutter plugin to handle gamepad input across multiple platforms.

A Flutter plugin to handle gamepad input across multiple platforms.
Note: This plugin is still in beta. All APIs are subject to change. Any feedback is appreciated.
Gamepads is a Flutter plugin to handle gamepad (or joystick) input across multiple platforms.
It supports multiple simultaneously connected gamepads, and will automatically detect and listen to new connections.
Getting Started #
The list
method will list all currently connected gamepads:
final gamepads = await Gamepads.list();
// ...
This uses the data class GamepadController
, which has an id
and a user-facing name
.
And the events
stream will broadcast input events from all gamepads:
Gamepads.events.listen((event) {
// ...
});
You can also listen to events only for a specific gamepad with eventsByGamepad
.
Events are described by the data class GamepadEvent
:
class GamepadEvent {
/// The id of the gamepad controller that fired the event.
final String gamepadId;
/// The timestamp in which the event was fired, in milliseconds since epoch.
final int timestamp;
/// The [KeyType] of the key that was triggered.
final KeyType type;
/// A platform-dependant identifier for the key that was triggered.
final String key;
/// The current value of the key.
final double value;
// ...
}
Next Steps #
As mentioned, this is still a WIP library. Not only APIs are expected to change if needed, but we plan to add more features, like:
- stream to listen for connecting/disconnecting gamepads
- get current state of a gamepad
- add support for web and even mobile

Android Integration #
The Android implementation requires the application's Activity to forward input events (and input devices) to the plugin. Below is an example of a MainActivity for a clean Flutter project that has implemented the required boilerplate code. For many projects it will be possible to simply duplicate this setup.
package [YOUR_PACKAGE_NAME]
import android.hardware.input.InputManager
import android.os.Handler
import android.view.InputDevice
import android.view.KeyEvent
import android.view.MotionEvent
import io.flutter.embedding.android.FlutterActivity
import org.flame_engine.gamepads_android.GamepadsCompatibleActivity
class MainActivity: FlutterActivity(), GamepadsCompatibleActivity {
var keyListener: ((KeyEvent) -> Boolean)? = null
var motionListener: ((MotionEvent) -> Boolean)? = null
override fun dispatchGenericMotionEvent(motionEvent: MotionEvent): Boolean {
return motionListener?.invoke(motionEvent) ?: false
}
override fun dispatchKeyEvent(keyEvent: KeyEvent): Boolean {
return keyListener?.invoke(keyEvent) ?: false
}
override fun registerInputDeviceListener(
listener: InputManager.InputDeviceListener, handler: Handler?) {
val inputManager = getSystemService(INPUT_SERVICE) as InputManager
inputManager.registerInputDeviceListener(listener, null)
}
override fun registerKeyEventHandler(handler: (KeyEvent) -> Boolean) {
keyListener = handler
}
override fun registerMotionEventHandler(handler: (MotionEvent) -> Boolean) {
motionListener = handler
}
}
