A practical guide to implementing multiple back stacks in Jetpack Compose Navigation3 for bottom navigation tabs. The pattern uses a Map of NavBackStack instances keyed by tab, combined with rememberSerializable for the current tab state. Each NavBackStack is preserved across recompositions even though the Map wrapper is recreated, eliminating the need for custom Savers or complex state holders. The approach covers tab switching, push navigation, back navigation, and retap-to-reset behavior in minimal code that matches standard Android app conventions.
