title: Flutter download file to phone download directory
body: <p>I have searched for similar questions and answers to this question but haven't found any specific answer till now.
  I am trying to save downloaded files to my internal phone storage. Preferably the download folder... Am using d i o and path provider.
  Have tried using  "get External Storage Directory". But even after the download I can't locate the file anywhere in my device.
  Please how do I specify the download path to something like /storage/emulated/0/Download</p>
