skeletix 1.0.1

A highly advanced, strictly declarative RenderObject automated skeleton generator. Intelligently scans layouts to automatically draw precision placeholders without rigid boilerplate.

SkeletiX 🚀

An absolute Set-and-Forget, highly performant, auto-analyzing skeleton loading engine for Flutter.

Unlike traditional skeleton packages that force you to manually rewrite "dummy" blocks mapping out your UI, SkeletiX climbs into your Native Render Tree natively. It intercepts Text, CircleAvatar, Image, Material Cards, and ElevatedButton leaf nodes geometrically and precisely masks them with beautifully animated Shimmer blocks without requiring ANY additional _isLoading layout changes from you!

Build your UI exactly once structurally using dummy Strings, wrap it in <SkeletiX>, and never think about loaders again.

🌟 Why use SkeletiX?

1. 100% Purely Declarative: No more _isLoading ? SkeletonBlock() : RealLayout() everywhere. Just pass loading: true onto the parent wrapper.
2. True Geometric Analysis: Intercepts low-level Flutter geometries (RenderDecoratedBox, RenderPhysicalShape, ShapeDecoration) via SingleChildRenderObjectWidget to trace exactly what is on the screen without touching layout spaces, paddings, or grid ratios natively.
3. Scroll-Locked Safety: Natively injects IgnorePointer during load phases. Completely blocks all touch events and viewport scrolling natively so users cannot accidentally click buttons or tear screen offsets before data stabilizes.
4. Instant Network Protections: Shipped alongside SkeletixImage, explicitly designed to prevent standard Image.network(null) crashes before URLs are fetched.
5. Built-in Error Handling: Seamlessly intercepts loading routines into full error views, supplying customizable onRetry buttons and totally custom Screen-swaps explicitly.

🛠️ Usage

1. Simple Drop-In

Wrap your pre-existing view entirely inside the SkeletiX engine.

SkeletiX(
  loading: _isLoading,
  error: _hasError ? "Failed to verify connection" : null,
  onRetry: () => _fetchData(), // Automatically renders a Try Again button!
  child: _buildMyComplexLayout(),
)

2. Handling Network Images Crash-Free

Standard Image.network natively throws unrecoverable Render Exceptions if passed a null URL before data hits.

Simply replace it with SkeletixImage! If the URL is null, it gracefully drops a transparent block which the SkeletiX Engine natively reads and turns into a precision-cut generic Skeleton Loader image box!

ClipRRect(
  borderRadius: BorderRadius.circular(12),
  child: SkeletixImage.network(
    product.imageUrl, // Perfectly safe if null!
    width: 200,
    fit: BoxFit.cover,
  ),
)

3. Dummy Data Sizing Rule

To generate structurally beautiful grid or list skeletons, the UI must physically take up layout space. If you supply Text(null ?? ''), Flutter collapses its width to 0.0, resulting in a tiny, empty box.

Supply standard mock strings/arrays while waiting for actual server data:

// The string 'Loading Title...' ensures the grid-card naturally keeps its padded layout shape!
final List<Product> _products = apiData?.products ?? List.generate(4, (_) => Product('Loading Title...', null));

...

Text(_products[index].title ?? '');

🎨 API Properties

Parameter	Type	Description
loading	bool	Instantly replaces textual leaves, avatars, and images with sweeping, frosty geometric shimmers. Locks all user touch/scroll events.
error	Object?	Replaces the view with a natively supplied Red Icon/Text error state. Instantly stops shimmer execution.
onRetry	VoidCallback?	Drops an automatic standard "Try Again" widget below your error string.
customErrorWidget	Widget?	Completely overrides the native string error view above. Take full customized control layout of failure states.
child	Widget	Your native, gorgeous, real screen layout logic requiring mapping!
