setStartHandler/setCompletionHandler are not called

💬 Questions and Help

I have an app in which I am trying to register callbacks to start/stop speak with the appropriate methods, but neither of them is called.

Might be related to #53, but I could not get what the issue was in that case.

Any assistance would be highly appreciated. Thank you.

  initTts() async {
    tts.setStartHandler(() {
      print("start");
      setState(() {
        ttsState = TtsState.playing;
      });
    });

    tts.setCompletionHandler(() {
      print("stop");
      setState(() {
        ttsState = TtsState.stopped;
      });
    });

@sashko I tested the registered callbacks again with the example in this repo and it's working. Please test with the example provided and let me know if it's failing and the emulator devices you're testing with.

Example app works. I have basically copy-pasted code, and have no idea what I would be missing....

I'm assuming it's because you're importing package:speak_nato/preferences.dart which is already instantiating FlutterTts. Maybe try passing your instance from your main_screen.dart into the preferences.dart like getLanguage(tts) and your preferences.dart containing Future<String> getLanguage(FlutterTts tts) async so you can remove var tts = new FlutterTts();.

Did my suggestion fix your issue @sashko ?

Apologizes for the delay - was away without my laptop.

You were right. Many thanks for your assistance!
