A dart library for zip files / streams.

Features

Currently only the decompression function is supported.

• Support for both AES and zip standard encryption methods
• Support for Zip64 format
• Store (No Compression) and Deflate compression method
• Extract files from split zip files (Ex: z01, z02,...zip)

Usage

// Open a zip file and paras header.
final zipFile = await ZipFile.file(File('path'));

// Gat all file headers.
final headers = zipFile.fileHeaders;

// Get a zip entry source.
final entrySource = await zipFile.getEntrySource(headers.first);

// Zip entry source can be read into memory or saved to a file.
...

// Close resource
await entrySource?.close();

Or use use and file_system:

final fileSystem = LocalFileSystem();
final zipFile = await ZipFile.file(fileSystem.file(path));
await zipFile.openRead().use((handle) async {
    for (final header in zipFile.fileHeaders) {
        await zipFile.getZipEntrySource(handle, header).use((source) =>
            fileSystem
                .openSink(join(output, header.fileName), recursive: true)
                .buffered()
                .use((sink) => sink.writeFromSource(source)));
    }
});
