Mic Info Plugin #

The Mic Info Plugin allows Flutter applications to retrieve information about connected microphones on Android and iOS devices, including active, default, wired, and Bluetooth microphones.

Features #

• Active Microphone Detection: Retrieve the active microphones that have an active recording in progress.
• Built-in Microphone Detection: Retrieve the default microphones available on the device.
• Wired and USB Microphone Detection: Detect wired headsets, including USB connector microphones.
• Bluetooth Microphone Detection: Identify and list Bluetooth microphones for hands-free audio input.
• Cross-Platform Support: Works seamlessly on both Android and iOS.

Platforms Supported #

• Android: API Level 24 (Android 7.0) and above.
• iOS: iOS 10.0 and above.

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 {
  // Retrieve Active Microphones
  List<MicInfoDevice> activeMicrophones = await MicInfo.getActiveMicrophones();
  print("Active Microphones: $activeMicrophones");

  // Retrieve Bluetooth Microphones
  List<MicInfoDevice> bluetoothMicrophones = await MicInfo.getBluetoothMicrophones();
  print("Bluetooth Microphones: $bluetoothMicrophones");

  // Retrieve Default Microphones
  List<MicInfoDevice> defaultMicrophones = await MicInfo.getDefaultMicrophones();
  print("Default Microphones: $defaultMicrophones");

  // Retrieve Wired Microphones
  List<MicInfoDevice> wiredMicrophones = await MicInfo.getWiredMicrophones();
  print("Wired Microphones: $wiredMicrophones");
}

MicInfoDevice Model #

The information about each microphone is returned as a list of MicInfoDevice objects. Each device contains:

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

Permissions #

Ensure that you have the appropriate permissions for accessing the microphone on both Android and iOS. This plugin doesn't handle permissions.

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.
