Please see the attached image. I have tried every way but unable to change the text to white.
You can see this in code:

  Theme(
            data: Theme.of(context).copyWith(
              iconTheme: const IconThemeData(color: Colors.white), // Icon color
              textButtonTheme: TextButtonThemeData(
                style: ButtonStyle(
                  foregroundColor: MaterialStateProperty.all(whiteColor),
                  // Text color
                  padding: MaterialStateProperty.all(
                    const EdgeInsets.symmetric(
                        horizontal: 20, vertical: 12), // Padding
                  ),
                  iconColor: MaterialStateProperty.all(Colors.white),
                  // Icon color
                  overlayColor:
                      MaterialStateProperty.all(Colors.white.withOpacity(0.2)),
                  // Ripple effect
                  shape: MaterialStateProperty.all(
                    RoundedRectangleBorder(
                      borderRadius: BorderRadius.circular(8), // Rounded corners
                    ),
                  ),
                ),
              ),
              dropdownMenuTheme: const DropdownMenuThemeData(
                // menuStyle: MenuStyle(
                //   backgroundColor:  WidgetStateProperty.all(whiteColor), // Text color
                //   padding: MaterialStateProperty.all(
                //     const EdgeInsets.symmetric(horizontal: 20, vertical: 12), // Padding
                //   ),
                // ),
                textStyle: TextStyle(
                    color: whiteColor), 
              ),
            ),
            child: Container(decoration: BoxDecoration(
              color: whiteColor.withOpacity(.3)
              // gradient: LinearGradient(colors: [whiteColor,whiteColor.withOpacity(.3)])
            ),
              child: QuillSimpleToolbar(

                    )
                  ),
                  fontFamily: QuillToolbarFontFamilyButtonOptions(
                    
                    iconTheme: QuillIconTheme(
                       iconButtonSelectedData: IconButtonData(color: whiteColor),

                  ),
                  controller: controller.quillCont,

                ),
              ),
            ),
          ),
      
      
      
      
          Expanded(
