Use case

Wanted to get disk usage of any folder in android, .thumbdata4-* type file under .thumbnails folder in DCIM reports its size as 10 Gb, but in actuality it takes only 12 Mb of space. So, didn't find any native way for flutter to report actual disk utilization.

Proposal

Add blocks count as well (number of blocks assigned to file) in FileStat, so that user can calculate actual size as well.
