Flutter Chat UI Files

This release introduces two-sided pagination. You can now load newer messages using the new onStartReached callback, while onEndReached continues to work for older messages. For pagination to work correctly, messages should be inserted instantly, without animation.

To allow this and offer more granular control, a new optional animated parameter has been added to all controller operations except update. This is not a breaking change, but if you'd like to use it, you can update your controller like so:

:::dart
insertMessage(Message message, {int? index}) // ❌
insertMessage(Message message, {int? index, bool animated = true}) // ✅
ChatOperation.insert(..., animated: animated) // add animated to insert operations

insertAllMessages(List<Message> messages, {int? index}) // ❌
insertAllMessages(List<Message> messages, {int? index, bool animated = true}) // ✅
ChatOperation.insertAll(..., animated: animated) // add animated to insertAll operations

removeMessage(Message message) // ❌
removeMessage(Message message, {bool animated = true}) // ✅
ChatOperation.remove(..., animated: animated) // add animated to remove operations

setMessages(List<Message> messages) // ❌
setMessages(List<Message> messages, {bool animated = true}) // ✅
ChatOperation.set(..., animated: animated) // add animated to set operations

As an optional improvement, you can use this parameter to disable animations when clearing the chat, which is now the default behaviour in the example apps.

:::dart
ChatOperation.set(messages, animated: messages.isEmpty ? false : animated) // inside the controller

⚠️ There is a small potential breaking change: LoadMoreNotifier was updated for two-sided loading. If you used a custom LoadMore widget and used LoadMoreNotifier to measure its height, that logic has been removed as it was not used. Additionally, the internal property _isLoading is now _isLoadingOlder, and _isLoadingNewer has been added.
