Sliver Expandable

Sliver Expandable lets expand and collapse any Sliver in Flutter.

Getting started

1. Add it to your pubspec.yaml:

sliver_expandable: ^1.1.0
                

2. Use it:

AnimatedSliverExpandable(
                  expanded: _expanded,
                  headerBuilder: (context, animation) => ListTile(
                    onTap: () => setState(() => _expanded = !_expanded),
                    tileColor: Colors.amber,
                    title: const Text('Expandable'),
                    trailing: AnimatedBuilder(
                      animation: animation,
                      builder: (context, child) => Transform.rotate(
                        angle: (animation.value - 0.5) * pi,
                        child: child,
                      ),
                      child: const Icon(Icons.chevron_left),
                    ),
                  ),
                  sliver: SliverList(
                    delegate: SliverChildBuilderDelegate(
                      (context, index) => ListTile(
                        title: Text('Expandable item no. $index'),
                      ),
                      childCount: 5,
                    ),
                  ),
                ),
