chat_ui/src/message_composer/cometchat_message_composer library
Re-export file for backward compatibility.
This file re-exports the CometChatMessageComposer widget from its new location in the widgets directory. This ensures existing imports continue to work without modification.
The actual implementation is now in:
widgets/cometchat_message_composer.dart
Classes
- AttachmentTile
-
One staged item in the tray, keyed by the app-supplied
fileId. - AttachmentTrayController
-
Owns the composer's staging model and drives the SDK's multi-upload surface:
a per-composer UploadFileRequest (
CometChat.createUploadFileRequest). - CometChatAttachmentErrorAlertStyle
- Styling for every attachment error alert the composer raises — one class for both surfaces, since they are the same notice in two places:
- CometChatAttachmentErrorSnackBar
- Shows an attachment's error reason as a SnackBar. Not a persistent widget — summoned on demand (tap) via show, from the ScaffoldMessenger above the composer.
- CometChatAttachmentTile
- One staged item in the CometChatAttachmentTray. Renders in one of three modes: • image / video → square thumbnail with a whole-tile status scrim • audio → inline player card — circular play button + seek slider + "pos/total" time; upload status lives inside the play circle (scrim + spinner / error badge) • file → wide card where status lives inside the leading icon container (scrim + spinner / error badge) plus a status subtitle ("PDF" / "Upload failed" / "Tap to retry")
- CometChatAttachmentTray
-
The composer strip that shows staged attachment tiles, rendered directly
above the input row. One CometChatAttachmentTile per
fileId(square thumbnails for image/video, an inline player card for audio, and a state-driven wide card for files — upload status inside the leading icon plus a status subtitle). Driven by an AttachmentTrayController; rebuilds as upload events arrive and renders nothing while empty. Sending is handled by the composer's own send button. - CometChatAttachmentTrayStyle
- CometChatAttachmentTrayStyle styles the composer's attachment staging tray and its tiles (media thumbnails, the audio player card and the file card). All fields are optional — null falls back to the tray's theme-driven defaults. Supports merge like every other UIKit style class.
- CometChatKeyboardDiagnostics
- Snapshot of every keyboard-related value the composer uses at a point in time. Consumers use this to diagnose device-specific spacing issues (extra gap between composer and keyboard, safe-area double-counting, etc.) without instrumenting the UIKit.
- CometChatMessageComposer
- CometChatMessageComposer component allows users to send messages and attachments to the chat, participating in the conversation.
Enums
- AttachmentTileStatus
- CometChatKeyboardDiagnosticsSource
- Source of a keyboard diagnostic event — lets consumers understand which code path inside the composer emitted the sample.
Typedefs
- CometChatKeyboardDiagnosticsCallback = void Function(CometChatKeyboardDiagnostics diagnostics)
- Signature for the keyboard diagnostics callback.
Exceptions / Errors
- AttachmentStageException
- Thrown by AttachmentTrayController.stage when a batch cannot be staged at all — the composer hasn't bound a conversation yet. The caller (composer) surfaces message to the user so the failure isn't swallowed silently. cause is the original error, when there is one.
