onEndReached function fired too many times about flutter_chat_ui HOT 7 CLOSED

Hi @UADACID the example is here https://docs.flyer.chat/flutter/chat-ui/advanced-usage#pagination you just need to add a boolean property, let's say _isRequesting (similarly to the example's _page) and set it to true before the request and to false after (after _page in the example).

Hi @gtu-myowin no, function should always be passed, otherwise chat will think there is no pagination. But inside the function, _handleEndReached, just don't fetch when _isRequesting is true, do an early exit. Chat will be trying to use _handleEndReached multiple times, but with the early exit nothing will be happening, and eventually if data will be loaded, _handleEndReached won't be triggered, cause new items will appear (will trigger again if you will continue scrolling) and if there will be an error, it will try to re-fetch again on pull.

Hi @infernowalker

Thanks you!

Of course it is being called many times, it is a developer's job to set requesting state, fire a request, update data source and set requesting to false :) only one request :)

Hi @demchenkoalex, I just wanted to be sure. Are you saying to fire onEndReached conditionally like this?

Chat(
	messages: _messages,
	onAttachmentPressed: _handleAtachmentPressed,
	onMessageTap: _handleMessageTap,
	onPreviewDataFetched: _handlePreviewDataFetched,
	onSendPressed: _handleSendPressed,
	showUserAvatars: true,
	showUserNames: true,
	user: _user,
	onEndReached: _isRequesting ? null : _handleEndReached, // I'm talking about this line.
	isLastPage: _isLastPage,
)

Thank you for your explanation. I will give it a try.
