ScrollController Exception
Closed this issue · 4 comments
The chatController is initialized as
chatController = ChatController(
initialMessageList: messageList,
scrollController: ScrollController(),
currentUser: currentUser!,
otherUsers: [otherUser!],
);
2. In the chatview, enter in incoming and receiving outgoing bubbles. Enough messages so that it has more messages than the height of the screen
3. Attempt to scroll up and down the view
Expected results:
Scroll without exceptions
Actual results:
Scroll with unlimited exceptions
I am on 2.0.0 and cannot update to newest version due to issues on that release.
Thank you for any assistance you can provide to resolve this issue.
@kkruel8100 I attempted to reproduce the issue but was unsuccessful. Could you please try it on the example and send me the steps to reproduce the issue along with the solution as soon as possible?
I am having the same issue, but it's a bit difficult to extract the code in a reproduceable manner.
I have a tab navigation and this usually shows up when I go from one tab to another (and one of the tabs is a chat view)
Could you please share the stack trace?
