A text to speech plugin for flutter. Initial implementation, more to come. :)


To use this plugin, add tts as a dependency in your pubspec.yaml file.


import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';

void main() {
  runApp(new Scaffold(
    body: new Center(
      child: new RaisedButton(
        onPressed: speak,
        child: new Text('Say Hello'),

speak() async {
  Tts.speak('Hello World');


You can get a list of available languages (voices) supported by the OS by calling:

final languages = await Tts.getAvailableLanguages();

Checking to see if a languge can be used:

var isGoodLanguage = await Tts.isLanguageAvailable(lang);

Setting a deisred language:

var setLanguage = await Tts.setLanguage(lang);

import 'package:flutter/material.dart';
import 'package:tts/tts.dart';
import 'dart:math';

void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
  _MyAppState createState() => new _MyAppState();

class _MyAppState extends State<MyApp> {
final TextEditingController speechTextController = new TextEditingController();
String languageAvailableText = '';
List<String> languages;
Random rng = new Random();
  initState() {

  // Platform messages are asynchronous, so we initialize in an async method.
  initPlatformState() async {
    // Platform messages may fail, so we use a try/catch PlatformException.
    languages = await Tts.getAvailableLanguages();
    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted)

  Widget build(BuildContext context) {
    return new MaterialApp(
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text('Plugin example app'),
        body: new Center(
          child: new Column(
            children: <Widget>[
              new TextField(
                controller: speechTextController,
              new MaterialButton(
                  onPressed: () async{
                    var lang = languages[rng.nextInt(languages.length-1)];
                    var isGoodLanguage = await Tts.isLanguageAvailable(lang);
                    var setLanguage = await Tts.setLanguage(lang);
                child: new Text('Do Speak'),
              new Text(languageAvailableText)
