### Install Flutter Serial Communication Package

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Installs the flutter_serial_communication package into your Flutter project. This can be done via the Flutter CLI or by manually adding it to your pubspec.yaml file.

```bash
flutter pub add flutter_serial_communication
```

```yaml
dependencies:
  flutter_serial_communication: 0.2.8
```

### Get Available Serial Devices in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Retrieves a list of all currently available serial devices connected to the Android device. This function is asynchronous and returns a list of DeviceInfo objects.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

List<DeviceInfo> availableDevices = await _flutterSerialCommunicationPlugin.getAvailableDevices();
```

--------------------------------

### Import Flutter Serial Communication in Dart

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Imports the necessary library into your Dart file to begin using its serial communication functionalities. This makes all the library's functions and classes available for use.

```dart
import 'package:flutter_serial_communication/flutter_serial_communication.dart';
```

--------------------------------

### Connect to a Serial Device in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Establishes a connection to a specific serial device using its DeviceInfo and a specified baud rate. This function is asynchronous and returns a boolean indicating the success of the connection.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

DeviceInfo device = DeviceInfo(); // DeviceInfo from getAvailableDevices()
int baudRate = 0; // Your device's baud rate
bool isConnectionSuccess = await _flutterSerialCommunicationPlugin.connect(device, baudRate);
```

### Listen for Serial Device Connection Status in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Sets up a listener to receive broadcast streams indicating the connection status of serial devices. This allows monitoring of device connections and disconnections.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

EventChannel eventChannel = _flutterSerialCommunicationPlugin.getDeviceConnectionListener();
eventChannel.receiveBroadcastStream().listen((event) {
  debugPrint("Received From Native:  $event");
});
```

--------------------------------

### Listen for Serial Messages in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Sets up a listener to receive broadcast streams of messages from the serial device. The received data is printed to the debug console.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

EventChannel eventChannel = _flutterSerialCommunicationPlugin.getSerialMessageListener();
eventChannel.receiveBroadcastStream().listen((event) {
  debugPrint("Received From Native:  $event");
});
```

--------------------------------

### Write Data to Serial Device in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Sends a list of bytes (Uint8List) to the connected serial device. This function is asynchronous and returns a boolean indicating whether the message was successfully sent.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

bool isMessageSent = await _flutterSerialCommunicationPlugin.write(Uint8List.fromList([0xBB, 0x00, 0x22, 0x00, 0x00, 0x22, 0x7E]));
debugPrint("Is Message Sent:  $isMessageSent");
```

--------------------------------

### Disconnect from Serial Device in Flutter

Source: https://github.com/farellsujanto/flutter_serial_communication/blob/main/README.md

Terminates the current serial connection. This function is asynchronous and does not return any value.

```dart
final _flutterSerialCommunicationPlugin = FlutterSerialCommunication();

await _flutterSerialCommunicationPlugin.disconnect();
```
