FileDownloadLoader class

FileDownloadLoader is a custom widget that visually simulates a file download process.

It takes the following parameters:

• totalSize : double - the total size of the file to download (in MB).

• downloadSpeed : double - the download speed (in MB/s).

The widget calculates the download progress over time and displays a progress bar along with the estimated time remaining until the download completes.

Example:

child: FileDownloadLoader(
 totalSize: file.size,
downloadSpeed: stream.downloadSpeed,
color : Colors.blue ,
);
This widget will create a progress bar that fills based on the download speed and total file size.
