BottomNavigationBar // Cannot control item label color

Goal: I want to give the item label a specific font and color depending on if it is selected or not.

My approach: As the label cannot be styled directly, I'm using the properties "unselectedLabelStyle" and "selectedLabelStyle".

The Problem:

• The properties work for font and fontweight, but I cannot directly control the text color
• I can influence the label color of the selected item; but not with the "selectedLabelStyle" property, but with the color I specifiy under "seltectedItemColor".
• "unselectedLabelStyle" also works for font and fontweight, but not for the color. I cannot find a property, that would allow me to change the color. > THIS IS THE PROBLEM

Pretty picture (code below):

The code:

BottomNavigationBar(
      elevation: 0,
      onTap: (index) => selectPage(index),
      currentIndex: selectedPageIndex,
      selectedItemColor:
          Provider.of<CustomColors>(context).customColorScheme['Dark Teal'],
      unselectedLabelStyle:
          Provider.of<CustomTextStyle>(context, listen: false)
              .customTextStyle('IconLabel'),
      selectedLabelStyle:
          Provider.of<CustomTextStyle>(context, listen: false)
              .customTextStyle('IconLabel'),
      backgroundColor: Colors.white,
      type: BottomNavigationBarType.fixed,
      items: [
        //home
        bottomNavIcon(
          context: context,
          icon: Image.asset(
            "assets/icons/icon_home.png",
          ),
          icon_active: Image.asset("assets/icons/icon_home.png",
              color: Provider.of<CustomColors>(context)
                  .customColorScheme['Dark Teal']),
          label: 'Home',
        ),
        //favorite
        bottomNavIcon(
          context: context,
          icon: Image.asset("assets/icons/icon_favorite.png"),
          icon_active: Image.asset("assets/icons/icon_favorite.png",
              color: Provider.of<CustomColors>(context)
                  .customColorScheme['Dark Teal']),
          label: 'Favorite',
        ),
        //loockback
        bottomNavIcon(
          context: context,
          icon: Image.asset("assets/icons/icon_lookback.png"),
          icon_active: Image.asset("assets/icons/icon_lookback.png",
              color: Provider.of<CustomColors>(context)
                  .customColorScheme['Dark Teal']),
          label: 'Lookback',
        ),
        //info & support
        bottomNavIcon(
          context: context,
          icon: Image.asset("assets/icons/icon_info.png"),
          icon_active: Image.asset("assets/icons/icon_info.png",
              color: Provider.of<CustomColors>(context)
                  .customColorScheme['Dark Teal']),
          label: 'Info & Support',
        ),
      ],
    ),

Code for the icons

BottomNavigationBarItem bottomNavIcon(
{required BuildContext context,
required Image icon,
required Image icon_active,
required String label}) {


return BottomNavigationBarItem(
    icon: Padding(
      padding: EdgeInsets.only(top: 6.h, bottom: 3.h),
      child: icon,
    ),
    activeIcon: Padding(
      padding: EdgeInsets.only(top: 6.h, bottom: 3.h),
      child: icon_active,
    ),
    label: label,
  );
}

If you want the unselected items to have a certain color, use:

unselectedItemColor: Colors.red,

This will change the color of label and icon both for unselected items.

Example:

Unfortunately, unselectedLabelStyle property works for changing font weight, font size etc but not for color.
