Spoiler

Spoiler widget for flutter.

HowTo:

child: Spoiler(openCurve: Curves.elasticOut,
               closeCurve: Curves.elasticIn,
               headerWhenSpoilerClosed: Text("Tools", style: TextStyle(color: Colors.white)),
               child: GameControl())

child: Spoilers(
         onUpdateCallback: (s) {
           print(s.childHeight);
           print(s.isOpened);
         },
         header: Text("Spoilers example header"),
         children: <Spoiler>[
           Spoiler(
             headerWhenSpoilerClosed: Text('First spoiler'),
               child: Text('Firsdt example context'),
           ),
           Spoiler(
             headerWhenSpoilerClosed: Text('Second spoiler'),
               child: Text('Second example context'),
           ),
         ],
       )

TODO:

• Custom header.
• Custom open header and custom close header.
• On open callback with header height and child height arguments.
• On close callback with header height and child height arguments.
• Get only header height for spoiler in spoiler widgets.
• Make Spoilers widget with callback that has all headers height and all child height.
• Add reverse parameter for change order of header and child.
• Add horizontal spoiler widget.
