Description

i constantly having this error log I/flutter (26641): Error fetching file: [firebase_storage/channel-error] Unable to establish connection on channel.

Reproducing the issue

this is the function that i am using firebase storage. The logic says that if the recognized word will be fetch in the storage corresponds a gif file.

void _onResult(SpeechRecognitionResult result) {
    setState(() {
      _wordsSpoken = result.recognizedWords;
      _confidenceLevel = result.confidence;
    });

    // Cancel the existing timer before starting a new one
    _speechTimeout.cancel();

    // Start a new timer if speech recognition is successful
    if (_confidenceLevel > 0) {
      _speechTimeout = Timer(const Duration(seconds: 2), () {
        _stopListening();
        // Fetch the URL after the timer stops
        String filePath =
            'gs://flutter-fsl.appspot.com/signlanguage/${_wordsSpoken.replaceAll(' ', ' ')}.gif';
        fetchFileFromStorage(filePath);
      });
    }
  }

  // void _onSubmitted(String value) {
  //   // Construct path based on the search query
  //   String filePath =
  //       'gs://salin-fsl.appspot.com/signlanguage/${value.replaceAll(' ', ' ')}.gif';
  //   fetchFileFromStorage(filePath);
  // }

  Future<void> fetchFileFromStorage(String filePath) async {
    // Check if the spoken word is not empty and the timer has stopped
    if (_wordsSpoken.isNotEmpty && !_speechTimeout.isActive) {
      try {
        final ref = FirebaseStorage.instance.ref(filePath);
        final url = await ref.getDownloadURL();

        // Set the URL to display after fetching
        setState(() {
          _imageUrl = url;
        });
        {
          print('File URL: $url');
        }
      } catch (e) {
        print('Error fetching file: $e');
        print('Word Spoken: $_wordsSpoken');
      }
    }
  }
