Browser crashes saving a large file

[thiagocarvalhodev]

I'm using this package to save a file on the default directory on Web. For small files, it works really well, but for large files (above 100Mb) it just crashes the Browser.

As it freezes and crashes, I can't provide a detailed log.

Tested:

• save a 1Mb file ✅
• save 10Mb ✅
• save 50Mb ✅
• save 80Mb ✅

After 100Mb, it begins to crash.

You can test trying to save a Uint8List of 100Mb

await FileSaver.instance.saveFile('file_name.txt', Uint8List(104857600), 'text/plain');

Using the version 0.1.1

@thiagocarvalhodev you can use this
https://github.com/eligrey/FileSaver.js/blob/master/src/FileSaver.js

also @incrediblezayed you can improve for web platform with this

I've been trying to integrate for a while now, I already removed method channel from web and I've added conditional imports, but currently I'm trying to integrate the js FileSaver for a while with whatever time I'm getting out of my other work, I hope I'll be able to do it this month.
And thank you

Actually this limitation is from flutter itself actually, flutter doesn't allows blob size greater than 100 MB

Hello,

currently in our environment web (chrome / edge, flutter: 3.19.3, filesaver 2.3.13)
we are able to save files up to about 320 MB, but 420 MB simply fails.
This issue does not exist on Firefox with the same build.

The 100 MB limit does not seem to exist anymore, but what is it now?
