coast

PageView wrapper supporting Hero-like animations

Example

Create a Coast with a number of Beaches and add a CrabController as observer to the Coast. Wrap a widget that you want to animate between beaches with a Crab widget with the same tag.

class CoastExampleApp extends StatefulWidget {
  @override
  _CoastExampleAppState createState() => _CoastExampleAppState();
}

class _CoastExampleAppState extends State<CoastExampleApp> {
  final _beaches = [
    Beach(builder: (context) => Cadzand()),
    Beach(builder: (context) => Westkapelle()),
    Beach(builder: (context) => Zoutelande()),
  ];

  final _coastController = CoastController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Coast(
        beaches: _beaches,
        controller: _coastController,
        observers: [
          CrabController(),
        ],
      ),
    );
  }
}


class Cadzand extends StatelessWidget {
  @override
  Widget build(BuildContext context) => Scaffold(
    appBar: AppBar(
      title: Text("Cadzand"),
      backgroundColor: Colors.deepOrange,
    ),
    body: Stack(
      children: [
        Positioned(
          top: 40,
          left: 40,
          child: Crab(
            tag: "container",
            child: Container(
              color: Colors.green,
              width: 80,
              height: 60,

          ),
        ),
      ],
    ),
  );

            ),
          ),
        ),
      ],
    ),
  );
}

class Zoutelande extends StatelessWidget {
  @override
  Widget build(BuildContext context) => Scaffold(
    appBar: AppBar(
      title: Text("Zoutelande"),
      backgroundColor: Colors.deepPurple,
    ),
    body: Stack(
      children: [
        Positioned(
          bottom: 40,
