How To Use

Can be used by encapsulating the child widget in a Skeleton widget:

import 'package:skeletons_forked/skeletons_forked.dart';

Skeleton(
        isLoading: _isLoading,
        skeleton: SkeletonListView(),
        child: Container(child: Center(child: Text("Content"))),
      )

or directly:

Container(
    child: _isLoading 
    ? SkeletonListView() 
    : Container(child: Center(
                       child: Text("Content"))),
)

a SkeletonTheme can be used to set the default configs for all skeleton descendants in the tree.

SkeletonTheme(
    // themeMode: ThemeMode.light,
    shimmerGradient: LinearGradient(
        colors: [
          Color(0xFFD8E3E7),
          Color(0xFFC8D5DA),
          Color(0xFFD8E3E7),
        ],
        stops: [
          0.1,
          0.5,
          0.9,
        ],
      ),
      darkShimmerGradient: LinearGradient(
        colors: [
          Color(0xFF222222),
          Color(0xFF242424),
          Color(0xFF2B2B2B),
          Color(0xFF242424),
          Color(0xFF222222),
        ],
        stops: [
          0.0,
          0.2,
          0.5,
          0.8,
          1,
        ],
        begin: Alignment(-2.4, -0.2),
        end: Alignment(2.4, 0.2),
        tileMode: TileMode.clamp,
      ),
        child: MateriaApp(
            ...
        ),
      ),

More Customization:

ListView (Complex Cards)

for more complex shapes you can build your skeleton inside a SkeletonItem widget:

ListView.builder(
  physics: NeverScrollableScrollPhysics(),
  itemCount: 5,
  itemBuilder: (context, index) => Padding(
    padding: const EdgeInsets.all(8.0),
    child: Container(
      padding: const EdgeInsets.all(8.0),
      decoration: BoxDecoration(color: Colors.white),
      child: SkeletonItem(
          child: Column(
        children: [
          Row(
            children: [
              SkeletonAvatar(
                style: SkeletonAvatarStyle(
                    shape: BoxShape.circle, width: 50, height: 50),
              ),
              SizedBox(width: 8),
              Expanded(
                child: SkeletonParagraph(
                  style: SkeletonParagraphStyle(
                      lines: 3,
                      spacing: 6,
                      lineStyle: SkeletonLineStyle(
                        randomLength: true,
                        height: 10,
                        borderRadius: BorderRadius.circular(8),
                        minLength: MediaQuery.of(context).size.width / 6,
                        maxLength: MediaQuery.of(context).size.width / 3,
                      )),
                ),
              )
