ZipReader class

Minimal hand-written ZIP reader that parses the End-Of-Central-Directory record and Central Directory File Headers to list entries, and reads individual entries' bytes via their Local File Header, using ZLibDecoder (raw-deflate mode) from dart:io (SDK-provided) for DEFLATE decompression. Supports STORED (0) and DEFLATE (8) methods only, which covers the overwhelming majority of zip/SCORM/office packages in practice.

This replaces the third-party archive package.

Static Methods

listEntries(File file) → Future<List<ZipEntry>>
Lists a zip archive's entries (names/sizes only — no content access; there is no readBytes on the result) by reading only its tail (the End-Of-Central-Directory record and Central Directory), never the whole file.
