large files showing in KB after uploading to google drive - php

Question

We are trying to use this plugin code in our php script
https://github.com/wp-plugins/google-drive-wp-media/tree/master/gdwpm-api
We modified code and using successfully in our project, But its working only for small files, When we upload large files to google drive files showing only in KB size.
May be only last chunk is uploaded to google drive for large files,
We tried to solve this error but failed, Please check and tell what we are doing wrong.
Here is our modified files.

As discussed in Upload Files, for reliable transfer especially important with larger files, using Resumable upload is a good strategy to use for most applications, since it also works for smaller files at the cost of one additional HTTP request per upload.
Additionally, apps that use resumable upload need to have code to resume an interrupted upload. If an upload is interrupted, find out how much data was successfully received, and then resume the upload starting from that point which is one of the good advantages of this uploading type.
For more information and steps in using resumable upload, kindly try going through given documentations above.
