Sticky date header #9

Open pierre-kci opened 1 year ago

pierre-kci commented 1 year ago

How could we keep these date header when scrolling down ? I've isolated body in a dedicated widget here : https://github.com/pierre-kci/flutter_gantt_chart/tree/isolating-body In order to remove date header from it just like for the stickyArea, This worked but splitted the hirontal scrolling in two, i.e. scrolling the events would not bring along the dates. Any suggestions would be mostly appreciated

this can be done using slivers and 2 horizontal listviews that share the same ScrollController

Wow, super cool ! How would you feel about adding a dependency to linked_scroll_controller ? I see another approach for multiple scrollable in sync using ScrollNotification but it looks trickier...

Clever approach for the slivers I might just start with this

I haven't really tried It, but I think that linked_scroll_controller looks easier
