attachment_engine_ios 0.0.1-dev.2

iOS implementation of attachment_engine providing native PDFKit, AVFoundation playback, QuickLook preview, download, and share.

0.0.1-dev.2

• Fixes openOfficePreview's Office/QuickLook QLPreviewController modal resolving its Dart future as soon as the preview was presented instead of when the user actually dismissed it, leaving callers with no signal to react to the close (e.g. to pop the screen behind the now-closed modal). It now implements QLPreviewControllerDelegate and only completes on previewControllerDidDismiss.

0.0.1-dev.1

• Initial release: the iOS implementation extracted from attachment_engine 0.1.0 as part of the federated-plugin split. Implements AttachmentEnginePlatform from attachment_engine_platform_interface on top of hand-written Swift (AVFoundation/AVPlayer, PDFKit, WKWebView, URLSessionDownloadTask-based resumable download, UIDocumentInteractionController/UIActivityViewController-based share/open).
• Migrates every request/response native call (PDF, audio/video control, share, open-externally, office preview, paths, download start/resume/cancel) from hand-written FlutterMethodChannel string dispatch to the pigeon-generated HostApi protocols in attachment_engine_platform_interface (Messages.g.swift). The audio/video/download event streams are unchanged, hand-written FlutterEventChannels.
