Crashing on iOS. about speech_to_text

[sowens-csd]

No issues I'm aware of right now. What version of iOS is it and do you know at what point it is crashing? While initializing? Listening? Other?

[GiovanniSybot]

Tested on Iphone 6 and 8.
It's not always, but when i press the button that triggets listen() method, the app just closes.
I'm developing in AndroidStudio, so i can't check any value on iOS.

[sowens-csd]

The iOS version of those two phones?
Is this with the example app or with your own app? If it is not with the example app could you try it with the example app and see if you still get crashes?

[GiovanniSybot]

One is iOS13, the other i dont know exactly but is 10+. I have one iPad with iOS9, that the plugin doesn't work, obviously.

[GiovanniSybot]

iOS13 and iOS12 the devices.

[GiovanniSybot]

I'm gonna post some code.

Future<void> initSpeechState() async {
bool hasSpeech = await speech.initialize(onError: errorListener, onStatus: statusListener );
if (!mounted) return;
setState(() {
_hasSpeech = hasSpeech;
});
}

void startListening() {
if (!_isListening){
lastWords = "";
lastError = "";
speech.listen(onResult: resultListener, localeId: locale, onSoundLevelChange: soundLevelListener);

  setState(() {
    _isListening = true;
  });
}

}

[GiovanniSybot]

RIP formatting.

[sowens-csd]

Can you get a crash log from the iOS device where the error is happening? Settings | Privacy | Analytics & Improvements | Analytics Data. There was an issue that caused an occasional crash when speech availability changed that was resolved in 0.8.0. But you say you're already using that version. Hopefully a crash log will provide some more help.

[GiovanniSybot]

That's all i got from the TestFlight report. The app just closes and nothing shows up.

[sowens-csd]

So you don't see a crash log in the on phone analytics? TestFlight doesn't always seem to include the details, not sure why, but they are usually on phone.

[GiovanniSybot]

Where can I find the log? I don't have an iPhone, and i'm not familiar with iOS.

[GiovanniSybot]

Thanks. Gonna check it as soon as possible.

[sowens-csd]

Any updates?

[GiovanniSybot]

Gonna check today.

[GiovanniSybot]

Did some runs on the iOS12 device, and got no crashes today.
But the onSoundLevelChange was not giving any results on iOS, only on Android.

I was not able to test on the iOS13 yet.

[sowens-csd]

Yes, the onSoundLevelChange is currently Android only. Been working on an iOS implementation but getting hung up on low level data access in Swift. Hopefully soon. Let me know when you think it's safe to close this issue.

[sowens-csd]

Thanks for the logs. Is that the complete log? Are these release builds or debug builds? I usually see more stack information, but that could be because I'm usually running debug builds.

I was just re-reading the thread and I'm not clear whether this is the example app or an app that you wrote? I think it's your app? If so could you try the example app on on one of the devices where this is happening?

[GiovanniSybot]

All release builds.

My app.

As i've said before, i don't have an iOS device to test the example, and I'm developing in AndroidStudio, so i have no clue from iOS behavior. I'm testing on iOS when someone here is with the phone available.

[GiovanniSybot]

Full log from latest crash.

Runner-2020-02-18-145812.txt

[sowens-csd]

Thanks the full log is more helpful. I don't see anything that immediately indicates it's related to speech_to_text. In Xcode you could likely load that crash report from TestFlight and see the symbols of the crash stack but other than that I'm not sure how to get more detail out of this. Another approach would be to try the example app on one of the devices that's having a problem and see if you can reproduce it to either rule speech_to_text in or out.

[GiovanniSybot]

Is there a way to 'dispose' the speech? I've noticed on iOS, as the plugin doesn't stop recording when you stop talking, like on Android, so when i return to the page it is still recording. And maybe it was causing a crash in some point... I've already fixed the recording making the speech to cancel when done, but i believe it needs to be closed properly in dispose() method.

[sowens-csd]

Now that's really interesting. I wonder if that could be causing the crash? You should always either cancel or stop the speech before leaving. Let me know if it continues to crash with this change?

There is no dispose required. Once speech is initialized you can't de-initialize or fully dispose of it. In my applications at least I do the initialization as part of the application start-up.

[GiovanniSybot]

I see, ok, now i'm forcing it to stop when you leave the page. Gonna make new features on the app, and next update i make more tests to check the behavior.

Thanks, let me know if you see any more crashes.
