different indicatorColor for each page

[mikle94]

Hello, I'm trying to change indicatorColor when pagingViewController didScrollToItem, but it doesn't work, it applies color from previous page. So I need to refresh it somehow. Here is what I've tried:

    private func setupView() {
        pagingViewController = PagingViewController<MenuItem>()
        pagingViewController.menuItemSource = .class(type: MenuItemPage.self)
        pagingViewController.menuItemSize = .fixed(width: UIScreen.main.bounds.width / CGFloat(menuItems.count), height: 87)
        pagingViewController.menuItemSpacing = 0
        pagingViewController.menuInsets = .zero
        pagingViewController.borderColor = .clear
        pagingViewController.indicatorColor = menuItems[0].color
        pagingViewController.indicatorClass = MenuIndicator.self
        pagingViewController.indicatorOptions = .visible(
            height: 3,
            zIndex: Int.max,
            spacing: .zero,
            insets: .zero
        )
        pagingViewController.borderOptions = .hidden
        addChildViewController(pagingViewController)
        view.addSubview(pagingViewController.view)
        view.constrainToEdges(pagingViewController.view)
        pagingViewController.didMove(toParentViewController: self)
        pagingViewController.dataSource = self
        pagingViewController.delegate = self
        pagingViewController.select(pagingItem: menuItems[0])
    }

func pagingViewController<T>(_ pagingViewController: PagingViewController<T>, didScrollToItem pagingItem: T, startingViewController: UIViewController?, destinationViewController: UIViewController, transitionSuccessful: Bool) where T : PagingItem, T : Comparable, T : Hashable {
    guard let item = pagingItem as? MenuItem else { return }
    pagingViewController.indicatorColor = item.color
}

Hi!

Pushed a fix now that should update the indicator when changing the options #245. Can you target the master branch and see if it works for you now? 🙂
