FlippableBox is a double-sided Container, that holds two pieces of content and automatically re-sizes to match its content, whenever its flipped over.
First import the package into your class:
Create a FlippableBox with two child Containers. Change the
isFlipped property to trigger the internal flip animation.
GestureDetector( onTap: () => setState(() => _isFlipped = !_isFlipped), child: FlippableBox( front: Container(width: 200, height: 200, color: Colors.white), back: Container(width: 300, height: 300, color: Colors.white), isFlipped: _isFlipped, ), )
NOTE: It is required that the children are Containers, and have their size or constraints set manually, as shown in the example above. This is so the Box knows what its target size is when animating.
To control the flip animation, you can set
flipVt which will cause the flip to be in the vertical axis rather than horizontal.
You can also specify a
bg which takes a BoxDecoration, and a
borderRadius in case you'd like to clip the child contents.
FlippableBox( front: child1, back: child2, isFlipped: _isFlipped, borderRadius: 32, //Uses a ClipRRect to clip contents of child containers bg: BoxDecoration(color: Colors.white), //Paints the box itself with a shared background duration: 0.5, //half second duration flipVt: true, //Flip vertically instead of horizontal curve: Curves.easeOut, )
See the example directory for a simple example.
