Status bar hide/show problem

[Utsabdeep Ray]

I am using sliverappbar on the homepage so it went to the top, then I gave safe area and status bar got visible which is grey. Now I want to give custom color to the status bar and I give 

"SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(statusBarColor: Color(0xffffd89b)));"

the whole app from splash screen to all are colored by this color.  Where I want to show and hide status bar to different pages. Like there will be no status bar for splash screen whereas a colored status bar to all other screens.
How to achieve it?
