W/TextToSpeech(11619): speak failed: not bound to TTS engine

🐛 Bug Report

I occasionally get this error

W/TextToSpeech(11619): speak failed: not bound to TTS engine

It's not very common, but when I get it I find I have to restart my entire app to get text-to-speech working again.

Just wondering if I am doing something incorrectly - otherwise perhaps there is a way I can detect this in code and restart the TTS engine (without having to restart the whole app) or something?

Many thanks for any help, and for this amazing lib! :)

Reproduction steps

Essentially (this more often than not works fine, but does fail once every so often):

flutterTts = FlutterTts();
await flutterTts.speak("my cool text");

Configuration

Version: 3.5.0

Platform:

• [ ] :iphone: iOS
• [x] :robot: Android

Just try to wait some time before calling speak, and you should be good. Use Future.delayed if convenient (might take around 500ms to initialize).

Thanks for the tip @chimura, will give this a go.
