Allow to change the background color of the SettingsItem widget

[Josee9988]

I'm using version 0.1.5 and I can only modify the background color of the icon. But not the background color of the tile/card itself.

Even though I tried to use backgroundColor, but it seems to be pointless...

My code

SettingsItem(
                  backgroundColor: Colors.red, // ignored
                  onTap: () {
                   ///
                  },
                  icons: Icons.foundation_outlined,
                  iconStyle: IconStyle(
                    backgroundColor: Colors.blueAccent,
                  ),
                  title: 'about_us'.tr(),
                  subtitle: 'meet_the_founders'.tr(),
                ),
