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.
