FlutterTTS flutterTts.awaitSpeakCompletion(true)设置失灵

awaitSpeakCompletion和awaitSyncCompletion都失效了，这个时候，还是用complete吧。

 

Completer completer = Completer();

flutterTts.setCompletionHandler(() {
  debugPrint("TTS 完成");
  if (!completer.isCompleted) completer.complete();
});

if (completeHandler != null) {
  flutterTts.setCompletionHandler(completeHandler);
}
await flutterTts.speak(str);
await completer.future;
