Fix: Prevent overriding child view presentation detents#48
Merged
Conversation
When NavigationStackFlow is initialized without the 'detents' parameter, it was applying .presentationDetents([]) (empty set) which incorrectly overrode presentation detents defined in child views. This change introduces OptionalPresentationDetentsModifier that only applies presentation detents when they are explicitly provided (non-nil), allowing child views to define their own detents without interference. Issue: - Child views using .presentationDetents() were being overridden - Sheets would open at maximum detent instead of specified heights - Close buttons and custom detent behaviors were broken Solution: - Replace .presentationDetents(navigationDetents ?? []) with conditional modifier - Only apply detents when explicitly provided via init parameter - Preserve backward compatibility for existing code
