  'SpeechToText',
  (result) => {

    if (result.error) {
      alert(JSON.stringify(result.error));
    } else {
      console.log(result.bestTranscription.formattedString);
    }

To stop recording call SpeechToText.finishRecognition() but after that you can continue to receive event with final recognition results. The events will not arrive after result.isFinal == true. Call SpeechToText.stopRecognition() to cancel current recognition task. The result objects reflects Apple SFSpeechRecognitionResult class.
