+This plugin provides simple recorder and player functionalities for both `android` and `ios` platforms. This only supports default file extension for each platform.
+This plugin handles file from remote url.
+This plugin can handle playback stream from native (To sync exact time with bridging).

+
+## Free Read
+[Medium Blog](https://medium.com/@dooboolab/flutter-sound-plugin-audio-recorder-player-e5a455a8beaf)
+
+## Getting Started
+For help getting started with Flutter, view our online
+[documentation](https://flutter.io/).
+
+## Install
+Add ```flutter_sound``` as a dependency in pubspec.yaml
+For help on adding as a dependency, view the [documentation](https://flutter.io/using-packages/).
+
+## Post Installation
+On *iOS* you need to add a usage description to `info.plist`:
+
+```xml
+<key>NSMicrophoneUsageDescription</key>
+<string>This sample uses the microphone to record your speech and convert it to text.</string>
+<key>UIBackgroundModes</key>
+<array>
+	<string>audio</string>
+</array>
+```
+
+On *Android* you need to add a permission to `AndroidManifest.xml`:
+```xml
+<uses-permission android:name="android.permission.RECORD_AUDIO" />
+<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
+```
+
+## Methods
+| Func  | Param  | Return | Description |
+| :------------ |:---------------:| :---------------:| :-----|
+| setSubscriptionDuration | `double sec` | `String` message | Set subscription timer in seconds. Default is `0.01` if not using this method.|
+| startRecorder | `String uri`, `int sampleRate`, `int numChannels` | `String` uri | Start recording. This will return uri used. |
+| stopRecorder | | `String` message | Stop recording.  |
+| startPlayer | `String uri` | `String` message | Start playing.  |
+| stopPlayer | | `String` message | Stop playing. |
+| pausePlayer | | `String` message | Pause playing. |
+| resumePlayer | | `String` message | Resume playing. |
+| seekToPlayer | `int milliSecs` position to goTo | `String` message | Seek audio to selected position in seconds. Parameter should be less than audio duration to correctly placed. |
+
+## Subscriptions
+| Subscription | Return | Description |
+| :------------ |:---------------:| :---------------:|
+| onRecorderStateChanged | `<RecordStatus>` | Able to listen to subscription when recorder starts. |
+| onPlayerStateChanged | `<PlayStatus>` | Able to listen to subscription when player starts. |
+
+
+## Default uri path
+When uri path is not set during the `function call` in `startRecorder` or `startPlayer`, they are saved in below path depending on the platform.
++ Default path for android
+  * `sdcard/sound.aac`.
++ Default path for ios
+  * `sound.aac`.
+
+## Usage
+#### Creating instance.
+In your view/page/dialog widget's State class, create an instance of FlutterSound.
+
+```dart
+FlutterSound flutterSound = new FlutterSound();
+```
+
+#### Starting recorder with listener.
+```dart
+Future<String> result = await flutterSound.startRecorder(null);
+
+result.then(path) {
+	print('startRecorder: $path');
+
+	_recorderSubscription = flutterSound.onRecorderStateChanged.listen((e) {
+	DateTime date = new DateTime.fromMillisecondsSinceEpoch(e.currentPosition.toInt());
+	String txt = DateFormat('mm:ss:SS', 'en_US').format(date);
+	});
+}
+```
+
+If you want to take your own path specify it like below.
+```
+String path = await flutterSound.startRecorder(Platform.isIOS ? 'ios.aac' : 'android.aac');
+```
+
+#### Stop recorder
+```dart
+Future<String> result = await flutterSound.stopRecorder();
+
+result.then(value) {
+	print('stopRecorder: $value');
+
+	if (_recorderSubscription != null) {
+		_recorderSubscription.cancel();
+		_recorderSubscription = null;
+	}
+}
+```
+
+You MUST ensure that the recorder has been stopped when your widget is detached from the ui.
+Overload your widget's dispose() method to stop the recorder when your widget is disposed.
+
+```dart
+@override
+void dispose() {
+	flutterSound.stopRecorder();
+	super.dispose();
+}
+```
+
+#### Start player
+To start playback of a recording call startPlayer.
+
+You must wait for the return value to complete before attempting to add any listeners
+to ensure that the player has fully initialised.
+
+```dart
+Future<String> result = await flutterSound.startPlayer(null);
+
+result.then(path) {
+	print('startPlayer: $path');
+
+	_playerSubscription = flutterSound.onPlayerStateChanged.listen((e) {
+		if (e != null) {
+			DateTime date = new DateTime.fromMillisecondsSinceEpoch(e.currentPosition.toInt());
+			String txt = DateFormat('mm:ss:SS', 'en_US').format(date);
+			this.setState(() {
+				this._isPlaying = true;
+				this._playerTxt = txt.substring(0, 8);
+			});
+		}
+	});
+}
+```
+
+#### Stop player
+
+
+```dart
+Future<String> result = await flutterSound.stopPlayer();
+
+result.then(value) {
+	print('stopPlayer: $result');
+	if (_playerSubscription != null) {
+		_playerSubscription.cancel();
+		_playerSubscription = null;
+	}
+}
+```
+
+You MUST ensure that the player has been stopped when your widget is detached from the ui.
+Overload your widget's dispose() method to stop the player when your widget is disposed.
+
+```dart
+@override
+void dispose() {
+	flutterSound.stopPlayer();
+	super.dispose();
+}
+```
+
+#### Pause player
+```dart
+Future<String> result = await flutterSound.pausePlayer();
+```
+
+#### Resume player
+```dart
+Future<String> result = await flutterSound.resumePlayer();
+```
+
+#### Seek player
+
+To seek to a new location the player must already be playing.
+```dart
+String Future<result> = await flutterSound.seekToPlayer(miliSecs);
+```
+
+#### Setting subscription duration (Optional). 0.01 is default value when not set.
+```dart
+/// 0.01 is default
+flutterSound.setSubscriptionDuration(0.01);
+```
+
+#### Setting volume.
+```dart
+/// 1.0 is default
+/// Currently, volume can be changed when player is running. Try manage this right after player starts.
+String path = await flutterSound.startPlayer(null);
+await flutterSound.setVolume(0.1);
+```
+
+#### Using the amplitude meter
+The amplitude meter allows displaying a basic representation of the input sound.
+When enabled, it returns values ranging 0-120dB.
+
+```dart
+//// By default this option is disabled, you can enable it by calling
+setDbLevelEnabled(true);
+```
+
+```dart
+//// You can tweak the frequency of updates by calling this function (unit is seconds)
+updateDbPeakProgress(0.8);
+```
+
+```dart
+//// You need to subscribe in order to receive the value updates
+_dbPeakSubscription = flutterSound.onRecorderDbPeakChanged.listen((value) {
+  setState(() {
+    this._dbLevel = value;
+  });
+});
+```
+
+### TODO
+- [ ] Seeking example in `Example` project
+- [x] Volume Control
+- [x] Sync timing for recorder callback handler

+When you face below error,
+```
+* What went wrong:

+# flutter_sound_example
+This is not a playlist audio module and this library provides simple recorder and player functionalities for both `android` and `ios` platforms. This only supports default file extension for each platform. This module can also handle file from url.
+
+## Getting Started
+
+For help getting started with Flutter, view our online
+[documentation](https://flutter.io/).
+
+## Install
+Add ```flutter_sound``` as a dependency in pubspec.yaml
+For help on adding as a dependency, view the [documentation](https://flutter.io/using-packages/).
+
+## Post Installation
+On *iOS* you need to add a usage description to `info.plist`:
+
+```xml
+<key>NSMicrophoneUsageDescription</key>
+<string>This sample uses the microphone to record your speech and convert it to text.</string>
+<key>UIBackgroundModes</key>
+<array>
+	<string>audio</string>
+</array>
+```
+
+On *Android* you need to add a permission to `AndroidManifest.xml`:
+```xml
+<uses-permission android:name="android.permission.RECORD_AUDIO" />
+```

+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
