alibabacloud_oss_sdk_dart

Added

• SealAppendObject: New API to seal an appendable object.
• XML Escape: Enhanced escape() to handle control characters (\t, \n, \r), other C0 control characters, and invalid XML characters.

Changed

• Object Tagging: Tag Key/Value are now XML-escaped during serialization.

Breaking Changes

• DeleteMultipleObjects: DeleteMultipleObjectsRequest no longer exposes top-level quiet/objects. Use the new nested delete: Delete(quiet: ..., objects: ...) instead.

Bug Fixes

• SignerV1: Fixed Content-MD5 / Content-Type header lookup to use lowercase keys (content-md5 / content-type), matching the lowercased header map produced by ClientImpl. Previously these headers were never found, causing them to always be empty in the StringToSign, which could result in SignatureDoesNotMatch errors from the server.
• SignerV1: Fixed canonicalizedOSSHeaders to check x-oss-* header count instead of total header count when deciding whether to append a trailing \n. Previously, when no x-oss-* headers were present but other headers existed (e.g. Date), an extra empty line was incorrectly added to the StringToSign, causing signature mismatches.

Improvements

• Updated package metadata for pub.dev, including repository and issue tracker URLs
• Added package badges and secure links in README.md and README-CN.md
• Added a top-level example/main.dart for package layout and pub.dev example detection
• Expanded dartdoc coverage across public API surfaces to improve generated documentation quality
• Refined formatting and package metadata to improve local pana validation results
