# Flyer Chat - Core Data Models

Core data structures are defined in `flutter_chat_core`.

## Message Model

- Base model for all message types.
- Defined in [message.dart](mdc:packages/flutter_chat_core/lib/src/models/message.dart).
- Contains common fields like `id`, `authorId`, `createdAt`, `roomId`, `type`, `metadata`.
- Includes nullable `DateTime?` fields for status tracking (`sentAt`, `deliveredAt`, `seenAt`, `failedAt`, etc.).
- Specific message types (Text, Image, File, Custom, System, etc.) extend or implement this base structure, often adding type-specific fields (e.g., `text` for `TextMessage`, `source` for `ImageMessage`).

## User Model

- Represents a user in the chat.
- Defined in [user.dart](mdc:packages/flutter_chat_core/lib/src/models/user.dart).
- Contains fields like `id`, `name`, `imageSource`, `role`, `metadata`.

## Other Models

- `ChatTheme`: Configuration for UI styling ([chat_theme.dart](mdc:packages/flutter_chat_core/lib/src/theme/chat_theme.dart)).
- `Builders`: Configuration for custom UI components ([builders.dart](mdc:packages/flutter_chat_core/lib/src/models/builders.dart)).
