lazy_indexed_stack_plus: ^0.0.1 copied to clipboard

The ultimate enhanced IndexedStack with lazy loading, preloading, and state preservation made easy for optimized Flutter apps.

Features #

• 🚀 Lazy Loading: Children are only built when they first become active.
• ⚡ Preloading: Specify indexes to load in the background before the user navigates to them.
• 💾 State Preservation: Keeps the state of children alive (scroll position, text inputs, etc.) once loaded.
• 🛠️ Custom Placeholders: Show a custom widget (like a loader) for uninitialized tabs.
• 🔄 Placeholder Sync: Automatically updates placeholders across all tabs if the placeholder widget changes.
