GzipDecoder class final

gzip (RFC 1952) decompression as a synchronous, chunk-driven state machine, including multi-member files (concatenated streams). Malformed input throws FormatException; the archive layer translates.

Trailer CRC-32 and ISIZE are verified per member by default (verifyChecksums). Trailing bytes after the last member that do not start with the gzip magic are ignored, matching gzip(1).

Constructors

GzipDecoder({bool verifyChecksums = true, void onMemberHeader(GzipMemberHeader header)?})

Creates the decoder. onMemberHeader is invoked with each member's parsed header (FNAME etc.) as decoding reaches it.

const

Properties

hashCode → int

The hash code for this object.

no setter, inherited

onMemberHeader → void Function(GzipMemberHeader header)?

Callback receiving each member's header metadata.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

verifyChecksums → bool

Verify each member's CRC-32 and ISIZE trailer (on by default).
