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

Example #

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');

Languages #

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);

var setLanguage = await Tts.setLanguage(lang);

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

  // 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.
