• pub.flutter-io.cn score: README.md is now English-primary (install/usage/ limitations), with the existing Chinese content moved to README.zh.md; install instructions updated to reflect that this package is now on pub.flutter-io.cn (previously documented as git-dependency-only).
• Added example/lib/main.dart (a minimal login/payment demo gated by MpWechat.isAvailable) and example/pubspec.yaml.
• Docs: added doc comments to the previously-undocumented fields and constructors of MpPaymentParams, MpAddress, MpScanResult, and MpLocation in lib/src/models.dart.

• pub.flutter-io.cn readiness: added homepage/repository/issue_tracker/topics, LICENSE (Apache-2.0), and this CHANGELOG.md. No API changes.
• Companion package mp_flutter (the build CLI) was renamed on pub.flutter-io.cn to flutter_miniprogram; this package's own name (mp_flutter_wechat) is unchanged.

Initial public release. WeChat login, payment, QR scanning, clipboard, location, sharing, and capsule-button APIs for Flutter apps compiled with mp-flutter; calling these APIs on other platforms throws a clear error instead of a platform-channel crash.
