I'm working on flutter list view, but I want it grouped list view with sticky header, side scrollbar and scroll to item (must provide jump to element, not particular on grouped) and that list view element have dynamic height and list may be long (10000 elements).
Basically, like whatsapp chat which is grouped by date with 2 additionally feature.

我在颤动列表视图上工作,但我希望它与粘性标题,侧滚动条和滚动到项目(必须提供跳转到元素,而不是分组的具体)列表视图元素有动态高度和列表可能是长的(10000个元素)分组列表视图。基本上,像WhatsApp聊天一样,它是按日期分组的,另外还有2个功能。



  1. side scrollbar (not like whatsapp which is goes up and down)

  2. jump to list view element (not scroll one by one) (element hv dynamic height).


I already tried flutter available library "scroll_to_index", "sticky_grouped_list", "scrollable_positioned_list" and many more, but none of them give desired output.
Please help me out, Thanks in advance.

我已经尝试过flutter可用库“scroll_to_index”,“sticky_grouped_list”,“scrollable_positioned_list”等等,但它们都没有给出所需的输出。请帮我一把,提前谢谢。
