To customize color options:

Desktop

Give a list of ColorOption to buildTextColorItem and/or buildHighlightColorItem functions to display your personalized colors.

       if (PlatformExtension.isDesktopOrWeb) {
            return FloatingToolbar(
              items: [
                buildTextColorItem(
                  colorOptions: [
                    ColorOption(colorHex: '164B60', name: 'Navy'),
                    ColorOption(colorHex: '1B6B93', name: 'Blue'),
                  ],
                ),
                buildHighlightColorItem(
                  colorOptions: [
                    ColorOption(colorHex: '4FC0D0', name: 'Light Blue'),
                    ColorOption(colorHex: 'A2FF86', name: 'Green'),
                  ],
                ),
              ],
          ...

Mobile

Give a list of text/background ColorOption to buildTextAndBackgroundColorMobileToolbarItem to display your personalized colors.

MobileToolbar(
                  editorState: editorState,
                  toolbarItems: [
                    buildTextAndBackgroundColorMobileToolbarItem(
                      textColorOptions: [
                        ColorOption(colorHex: '164B60', name: 'Navy'),
                        ColorOption(colorHex: '1B6B93', name: 'Blue'),
                      ],
                      backgroundColorOptions: [
                        ColorOption(colorHex: '4FC0D0', name: 'Light Blue'),
                        ColorOption(colorHex: 'A2FF86', name: 'Green'),
                      ],
                    ),
                  ],
                ),

@hyj1204 Please fix the CI issues.

Does this ever get assigned any other value than null? Seems redundant

[hyj1204]

highlightColorHex is used to show a checked mark on current color options(if it has a color), I assigned value to it now(same with text color).

Nice catch, Thanks!
