child:  Scaffold(
        floatingActionButtonLocation: FloatingActionButtonLocation.endFloat,
        extendBody: true,
        body: screens[index],
        bottomNavigationBar: Theme(
          data: Theme.of(context)
              .copyWith(iconTheme: IconThemeData(color: Colors.white)),
          child: CurvedNavigationBar(
            items: items,
            index: index,
            height: 55,
            color: Colors.indigo,
            backgroundColor: Colors.white,
            buttonBackgroundColor: Colors.indigo,
            onTap: (index) => setState(() => this.index = index),
          ),
        ),
        floatingActionButton: _playerControl(context), //this contains the mini 
          player. I want this to be hidden or present based upon the value received 
          by url argument
      ),
    );

    You can perform a condition check to do this:

    
floatingActionButton : (title.isNotEmpty)?_playerControl(context) : null,
