codifyiq_chat_attachments 1.0.0

Image, file and video message bubbles for flutter_chat_ui that open the CodifyIQ image, PDF and video viewers.

1.0.0

• Initial release.
• ChatAttachments — image, file, video and audio message builders for flutter_chat_ui. Hand them to Builders with apply, or one at a time. Share and Download in the viewers call back with the message they belong to, and HTTP headers can be set per message for private storage.
• Sources can be network URLs, blob: URLs on the web, and local paths or file:// URIs elsewhere, plus bundled assets (assets/...) and data: URIs for images — the same as flutter_chat_ui's own bubbles.
• Images open codifyiq_image_viewer with a Hero, paging through every image in the conversation (or only the one tapped, with ChatImageGallery.message).
• PDFs open codifyiq_pdf_viewer's PdfViewerScreen; other files call onOpenFile.
• Videos open codifyiq_video_viewer's VideoViewerScreen, with an optional poster and duration on the bubble.
• Thumbnails: an image with a thumbnail (ChatAttachmentMetadata.thumbnail in its metadata, or imageThumbnail) loads only that in the chat, and the viewer shows it until the full image arrives. Without one, the full image is decoded no larger than the bubble, and opening it reuses the download. Network images are cached on disk through the CrossCache that Chat provides, like flutter_chat_ui's own image bubble. Videos read their poster and length from the metadata too.
• Messages that are sending are dimmed with a progress ring that follows updateUploadProgress on the chat controller, and messages that failed to send are marked.
• Audio messages play in their bubble with codifyiq_audio_message, showing their length before loading. Share one audioController across the chat so one message plays at a time and keeps playing when its bubble scrolls out of view.
• Bubbles take their colours, shape and text styles from flutter_chat_ui's ChatTheme, and show the message's time and status below the picture or file, on a line of their own or beside the caption (showTime, showStatus, timeAndStatusPosition), like flutter_chat_ui's own bubbles.
• openOnTap: false leaves taps to Chat's onMessageTap, for selection or retrying failed messages; openImage, openPdf and openVideo open attachments yourself. Long presses and double taps reach Chat either way.
• Images show their thumbhash as a blurred placeholder, take its rough shape when the message has no size until the image loads and gives its own, fade in, and show imageOverlay when the message has hasOverlay. imageErrorBuilder replaces the broken-image icon.
• topWidget adds a widget above any bubble, such as the author's name; fileIcon picks file icons; maxHeight and borderRadius size and shape the bubbles; labels localises the text they show and announce.
• actions adds your own entries to the viewers' menus, and routeBuilder sets the route the viewers open in.
• ChatImageAttachment, ChatFileAttachment, ChatVideoAttachment and ChatAudioAttachment — the bubbles on their own, for custom builders.
