Found a fix for now.

• Open the DatePicker class (Control+click)
• Comment this line // theme: Theme.of(context, shadowThemeOnly: true),

For this you have to fork the whole repo of date picker.. You cannot access or modify file which you are using in your project through reference

If you've use this plugin in one or two projects then modifying the local project files is just easier and faster. And yes, any plugin can be modified direct in code.
