Need a flutter widget with code (3-4 screens) with dark and light theme.

I need a widget in the flutter code which will accepts this json as input [login to view URL] - show a title, description, - location, category - Job Featured (until the datetime in the json) - Job highlighted (until the datetime in the json) - Only if it's not removed (check the json) - button to send a message -> Populate the default messages to send -> Click Send (no functionality with sending, I will work on them) - If JSON has datetime timestamp for inactive or removal - show the status Inactive or Deleted. - button to report -> Open a form to report -> Submit (no functionality when submit, I will work on them) - Users can like unlike the screen - User's pic who created this form (use any asset image) - Image carousel (just leave that widget empty, because I already have this) - Map to show the location of the screen (check geoloc in the json) - Distance from the user (Just keep the text, I will work on the functionality) Widget must be - Responsive ([login to view URL]) - Having the data classes ([login to view URL]) - All the screen must be stateless - Must use getx state management for updating the stateless widgets - You must use the Sliver Widgets - Do not have a list inside the list - Do not use the shrinkwrap=true - Make sure performance-wise it's working fine - Must have both Dark and Light theme
