What is an EventChannel, and how does it genuinely differ from a MethodChannel specifically in terms of properly supporting an ongoing continuous stream of native events rather than just one single request and response?

While a MethodChannel is genuinely designed for a single one off request and its own corresponding single response, an EventChannel is specifically designed to support an ongoing continuous stream of native events being pushed from the native side over to Dart, such as continuously streaming sensor readings or ongoing battery level change notifications, and Dart properly receives these particular ongoing events as a genuine Dart Stream, letting you use the exact same familiar StreamBuilder or listen pattern already used elsewhere throughout Flutter to properly react to each individual incoming native event as it genuinely actually arrives.

static const eventChannel = EventChannel('com.example.app/battery-updates');
eventChannel.receiveBroadcastStream().listen((batteryLevel) {
  print('Battery level changed: $batteryLevel');
});
