Flutter Android PIXEL Emulator - _platformCallHandler call speech.onError 2

[mingxun]

I have the same issue when running on simulator. But it works fine on real device. Hope this helps other people who got the same issue.

Looks like after google search I found Error code 2 means Network_error. Still not sure how to fix it in android-emulator x86 in Flutter.

And here is the complete code file Flutter

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

class SpeechBot extends StatefulWidget {
@OverRide
_SpeechBotState createState() => new _SpeechBotState();
}

class _SpeechBotState extends State {
SpeechRecognition _speech;

bool _speechRecognitionAvailable = false;
bool _isListening = false;

String transcription = '';

String _currentLocale = 'en_US';

@OverRide
initState() {
super.initState();
activateSpeechRecognizer();
}

// Platform messages are asynchronous, so we initialize in an async method.
void activateSpeechRecognizer() {
print('_SpeechBotState.activateSpeechRecognizer... ');
_speech = new SpeechRecognition();
_speech.setAvailabilityHandler(onSpeechAvailability);
_speech.setCurrentLocaleHandler(onCurrentLocale);
_speech.setRecognitionStartedHandler(onRecognitionStarted);
_speech.setRecognitionResultHandler(onRecognitionResult);
_speech.setRecognitionCompleteHandler(onRecognitionComplete);
_speech
.activate()
.then((res) => setState(() => _speechRecognitionAvailable = res));
}

@OverRide
Widget build(BuildContext context) {
return new MaterialApp(
