Is there anyway to stream audio data in flutter using api?

API
1

I am building something and i need it to use openai tts in my flutter app
Everything is good but the audio response can take some time sometimes.
So it would be nice if i can stream it but coundnt find any documentation to stream with api.
Please help if you have any idea

You can just start playing the audio file as soon as some of the chunks have been downloaded.

instead of using file i am using direct bits to play it without it needing to download to a file

  Future<Uint8List> generateAudioFromText(String text, String voice) async {
    final url = Uri.parse(AppConstants.openAISpeech);
    final headers = {
      'Authorization': 'Bearer ${AppConstants.openAIApiKey}',
      'Content-Type': 'application/json',
    };
    final body = jsonEncode({
      'model': 'tts-1',
      'input': text,
      'voice': voice,
    });

    final response = await http.post(url, headers: headers, body: body);
    if (response.statusCode == 200) {
      return response.bodyBytes;
    } else {
      throw Exception('Failed to generate audio: ${response.body}');
    }
  }

That should work too.

Quick question, doesn’t this expose your OpenAI API key? How do you make sure it’s safe without using any backed/middleware service?
