• #12 Add more control to how how scroll position is preserved across tabs in relation to the growing and shrinking of the header. When creating MaterialTabsScroll, provide an optional MaterialTabsConfig and specify the crossTabSyncMode as follows (the default is resetTitleOnScroll():

    /// Specifies how the scroll view and header adjust to maintain continuity when switching tabs. These options affect one specific scenario. Suppose
    /// we have two tabs A and B and a collapsible title view:
    ///
    ///   1. User scrolls down (a.k.a swipes up) in tab A such that the title view is collapsed.
    ///   2. User switches to tab B and scrolls up (a.k.a swipes down) until the title view is expanded
    ///   3. User switches back to tab A
    ///
    /// Since the title view is expanded on tab A, but it would have naturally been collapsed, there are multiple strategies for how continuitity is preserved.
    public enum CrossTabSyncMode: Equatable {
        /// Preserves the scroll position relative to the header. If the header has moved up, the scroll view is moved up. If the header is moved down, the scroll
        /// view is moved down. The benefit of this approach is preserving the user's scroll position. The down side is that the header is expanded when it
        /// should be collapsed and will remain expanded if the user scrolls up, which could severely limit the space for scroll view content if the header
        /// is unusually tall.
        case preserveScrollPosition
        /// Resets the scroll position to align the top of the scroll view content is aligned with the bottom of the header. This is how many apps behave and
        /// it ensures that scroll position and title collapse state are always in sync. The down side is that the user's previous scroll position is lost.
        case resetScrollPosition
        /// Initially preserves the scroll position the same as `preserveContentOffset`. However, if the user scrolls, the title collapse state is
        /// animated to where match the scroll position. This option introduces a title view animation, but eliminates the down sides of other options.
        /// This is the default behavior.
        case resetTitleOnScroll(_ animation: Animation = .snappy(duration: 0.3))
    }

Fixes

• Fix #17 tab bar doesn't animate when switching tabs
• Fix #9 Fix issue where appearing tab doesn't have its content offset adjusted to be in sync with the header until after it appears. This was causing a visible content offset jump when swiping slowly to a new tab. The fix only works on iOS 18+.

Bug fix

Fixes

• Fix #17 Animate tab bar scroll position changes

iOS 18 fix

• Fix #12 Scroll doesn't reset when switching the tabs while scrolled to top
• Fix the bottom padding on MaterialTabsScroll in iOS 18

New tab bar layout options

Improvements

• Add two new configuration options to MaterialTabBar that can be useful when implementing custom tab labels:
  • fillAvailableSpace: Applicable when tab labels don't inherently fill the width of the tab bar. When true (the default), the label widths are expanded proportinally to fill the tab bar. When false, the labels are not expanded and centered horizontally within the tab bar.
  • spacing: The amount of horizontal spacing to use between tab labels. Primary and Secondary tabs should use the default spacing of 0 to form a continuous line across the bottom of the tab bar.

2.0.0

• Add a context argument to the MaterialTabsScroll and StickyHeaderScroll view builders, providing useful metrics, such as the available safe height for content under the header.
