Cannot Zip large file

[duchieupham]

I'm facing with zipping large file on windows OS and MacOS. If I have a zip file larger than 2Gb, my application crashes when starting zip process. If I have a file large than 2Gb, the zip process seems to have errors. My zip file has just 75-80 bytes size.

You can try using an InputFileStream with the ZipDecoder.

import 'package:archive/archive_io.dart';
void main() {
    var stream = InputFileStream('large_zip_file.zip');
    var zip = ZipDecoder().decodeBuffer(stream);
    for (var file in zip.files) {
        var fileData = file.content;
        // do something with the file data
        file.clear(); // clear the memory
    }
}
