Example

To use this plugin :

• add the dependency to your pubspec.yaml file.

  dependencies:
    flutter:
      sdk: flutter
    flutter_tts:

• instantiate a FlutterTts instance

FlutterTts flutterTts = new FlutterTts();

speak, stop, getLanguages, setLanguage, setSpeechRate, setVolume, setPitch, isLanguageAvailable

Future _speak() async{
    var result = await flutterTts.speak("Hello World");
    if (result == 1) setState(() => ttsState = TtsState.playing);
}

Future _stop() async{
    var result = await flutterTts.stop();
    if (result == 1) setState(() => ttsState = TtsState.stopped);
}

List<dynamic> languages = await flutterTts.getLanguages;

await flutterTts.setLanguage("en-US");

await flutterTts.setSpeechRate(1.0);

await flutterTts.setVolume(1.0);

await flutterTts.setPitch(1.0);

await flutterTts.isLanguageAvailable("en-US");

Listening for platform calls

flutterTts.setStartHandler(() {
  setState(() {
    ttsState = TtsState.playing;
  });
});

flutterTts.setCompletionHandler(() {
  setState(() {
    ttsState = TtsState.stopped;
  });
});

flutterTts.setErrorHandler((msg) {
  setState(() {
    ttsState = TtsState.stopped;
  });
});
