Usage #

Import the Plugin #

To use this plugin, import it in your Dart file:

import 'package:mic_info/mic_info.dart';

Example: Retrieving Microphone Information #

You can retrieve information about the default, wired, and Bluetooth microphones using the following methods:

import 'package:mic_info/mic_info.dart';
import 'package:mic_info/model/mic_info_model.dart';

void getMicrophoneInfo() async {
  final micInfo = MicInfo();

  // Retrieve Default Microphone
  List<Device> defaultMicrophones = await micInfo.getDefaultMicrophone();
  print("Default Microphones: $defaultMicrophones");

  // Retrieve Wired Microphone
  List<Device> wiredMicrophones = await micInfo.getWiredMicrophone();
  print("Wired Microphones: $wiredMicrophones");

  // Retrieve Bluetooth Microphone
  List<Device> bluetoothMicrophones = await micInfo.getBluetoothMicrophone();
  print("Bluetooth Microphones: $bluetoothMicrophones");
}

Device Model #

The information about each microphone is returned as a list of Device objects:

class Device {
  String productName;
  String id;

  Device({required this.productName, required this.id});

  @override
  String toString() {
    return 'Device(productName: $productName, id: $id)';
  }
}

Each device contains:

• productName: The name of the microphone.
• id: The unique identifier of the microphone.

Permissions #

Ensure that you have the appropriate permissions for accessing the microphone on both Android and iOS.

Android

Add the following permission in your AndroidManifest.xml file:

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

iOS

In the ios/Runner/Info.plist file, add:

<key>NSMicrophoneUsageDescription</key>
<string>This app needs access to your microphone.</string>

Platform-Specific Implementation #

Android #

This plugin uses AudioManager and AudioDeviceInfo to detect connected microphones on Android devices.

iOS #

For iOS, the plugin uses AVAudioSession to retrieve microphone information, including Bluetooth and wired devices.

Troubleshooting #

-Ensure that the app has permission to use the microphone. -Check that the connected microphones are supported by your device.
