@its-me-abhishek , I am thinking of implementing #441 in this PR which will have only one bottom sheet for both 2.0 and 3.0

[its-me-abhishek]

hey! imo separate bottomSheets should be better for differentiation (or you can try using visibility widget along with isTaskcEnabled bool, but please make sure that it does not break something) as CCSync does not support adding dates such as sched, until, wait, etc for tasks. Also, you should look into #441 before doing this (if you are interested in developing that), as yet again the bottomsheet would need to be updated for adding tags functionality.
P.S. The tags functionality has been added to CCSync via this issue

Edit: The screenshots suggest that the theme should also be fixed according to the Color scheme of the app

Yes, I am thinking of implementing #441 by this PR (typo in previous comment wrote 414 instead of 441)
Theme is yet to be done, when #402 will be merged it'll reduce the code

update: tags functionality added which can close #441
