1. Decoration added for search box dialog

I'm using this package while doing my internship. There is this problem occurring when I try to implement CSC Picker, problem is as follow:

1. The background color of the search box dialog is getting change as the theme I described in main.dart
2. I'm not able to change the background color of Search box dialog after it is changed automatically by implementing theme.

SOLUTION: First solution was to write my own package for this but it is difficult task I choose to modify code and did my job.

Code changes: ClipRRect is replaced with the Container with the customizable decoration parameter (searchDialogDecoration).
