⚠️ Breaking changes ⚠️

• Updated the Message model to rename parentId to replyToMessageId
• The createdAt field is now optional in the message model
• The sending field has been removed from the message model; instead, you can set sending: true in the metadata of the Message model to achieve the same functionality.
• The isOnlyEmoji property has been removed from the text message model; to indicate that a message contains only emojis, use isOnlyEmoji: true in the metadata of the text message.
• The firstName and lastName fields in the User model have been consolidated into a single name field for improved simplicity.

Other changes

• Introduced MessageID and UserID typedefs to provide clearer context, while maintaining their underlying type as Strings
• Introduced TextStreamMessage type to support text streaming
• Added textStreamMessageBuilder to the Builders class to support text streaming UI widget

0.0.11

⚠️ Breaking changes ⚠️

0.0.10

⚠️ Breaking changes ⚠️

• Requires Freezed 3.0.0
• Replace status field with a computed getter that determines message state based on lifecycle timestamps (createdAt, deletedAt, sending, failedAt, sentAt, deliveredAt, seenAt, updatedAt). This enables granular message history tracking and status transitions, matching the behavior of popular chat applications.
• Rename overlay to hasOverlay in ImageMessage

Other changes

• Downgrade intl package version for better compatibility with other Flutter packages

0.0.9

• Added system message for displaying system notifications and events in chat

0.0.8

• Add UserCache class to store resolved users for synchronous access, preventing flickering in recycled widgets by caching user data with LRU eviction strategy
• Add ScrollToMessageMixin to enable programmatic scrolling in chat list:
  • scrollToMessage(messageId): Scrolls to a specific message by ID
  • scrollToIndex(index): Scrolls to a message at a specific index
  • Both methods support customizable animation duration, curve, alignment and offset
  • Can be used directly through any ChatController instance
  • See the pagination example in the example project for usage details
• Add validation to prevent duplicate message IDs

0.0.7

• Require Flutter 3.29 and Dart 3.7

0.0.6

⚠️ Breaking changes ⚠️

• Changed signature of chatMessageBuilder to include isRemoved and groupStatus parameters.
• Changed imageUrl to imageSource for the User model. Change is necessary to show that not only remote URLs are supported but also local assets.

0.0.5

⚠️ Breaking changes ⚠️

🔄 Core Changes:

• author (type User) is replaced with authorId (type String) for simpler user management
• All DateTime properties now use milliseconds instead of microseconds for JSON serialization

🎨 Theme Simplification: Theme has been streamlined to 3 key parameters:

1. colors - Uses Material 3 semantic names (e.g. primary, onPrimary, secondary) making it easy to apply color schemes
2. typography - Follows Flutter's TextTheme semantic naming conventions
3. shape - Controls border radius of all messages (rounded vs square messages)

✨ Enhanced Customization:

• Individual widget customization available through the builders parameter
• Example: loadMoreBuilder: (context) => LoadMore(color: Colors.red) overrides theme colors
• Full widget customization possible by returning custom widgets from builders

0.0.4

• Added isOnlyEmoji parameter to TextMessage.
• Message builders now include the message index in their parameters.
• Reverted withValues to withOpacity to resolve a compatibility issue.

• Added overlay parameter to ImageMessage
• Themes:
  • Added ImageMessageTheme (replacing imagePlaceholderColor)
  • Updated InputTheme (adding textFieldColor)
  • Updated ScrollToBottomTheme
  • Updated TextMessageTheme
• Added UploadProgressMixin for handling upload progress tracking
