Convert speech to text in flutter for desktop(Windows) application - flutter

I am developing a cross platform application in flutter and cannot find any sources for converting speech to text in desktop(windows).
I tried using packages like speech_to_text
I even tried google_speech in which it require an audio file to transcribe it to text. But, I could not find any package for taking microphone input in windows so that I can pass it to an API and get the text.
Is there any possible solution for this?
