Code sample is

import 'dart:async';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
import 'package:flutter_tts/flutter_tts.dart';

class Transliterate extends StatefulWidget {
final String _storyID;
final String o_text;
final FlutterTts flutterTts ;

Transliterate(this._storyID, this.flutterTts, String o_text) : o_text = o_text;

@OverRide
_TransliterateState createState() => _TransliterateState();
}

enum TtsState { playing, stopped, paused, continued}

class _TransliterateState extends State {
CollectionReference stry = FirebaseFirestore.instance.collection('stories');
String? txt;
String? language;
double volume = 0.5;
double pitch = 1.0;
double rate = 0.5;

TtsState ttsState = TtsState.stopped;

get isPlaying => ttsState == TtsState.playing;
get isStopped => ttsState == TtsState.stopped;
get isPaused => ttsState == TtsState.paused;
get isContinued => ttsState == TtsState.continued;

Future _speak() async {
await widget.flutterTts.setVolume(volume);
await widget.flutterTts.setSpeechRate(rate);
await widget.flutterTts.setPitch(pitch);

//for testing
// FlutterTts flut = FlutterTts();
// String text = "एका जंगलात एक छोटं जलाशय होतं त्यामध्ये एक बेडूक राहत होता त्याला एकटेपणा जाणवत होता त्यासाठी.";
// await flut.setLanguage("mr-IN");
// await flut.setVolume(0.5);
// await flut.setSpeechRate(0.5);
// await flut.setPitch(1);
// await flut.speak(text);
// print(text);

if (language == "Gujarati") widget.flutterTts.setLanguage("gu-IN");
if (language == "Bengali") widget.flutterTts.setLanguage("bn-IN");
if (language == "Telugu") widget.flutterTts.setLanguage("te-IN");

print(language);
await widget.flutterTts.awaitSpeakCompletion(true);
var result = await widget.flutterTts.speak(txt!);
if (result == 1) setState(() => ttsState = TtsState.playing);

}

Future _stop() async {
var result = await widget.flutterTts.stop();

}

Future _pause() async {

}
