EasyDialogDecoration<D extends EasyDialog> class abstract base Decorations Migration guide from 2.x to 3.x

This class is intended to be used by D dialog to apply some decorations.

This can be useful if you want to customize the appearance or behavior of your dialog's content.

Example:

Define some sort of dialog decoration:

final class CustomPositionedAnimation
  extends EasyDialogDecoration<PositionedDialog> {
@override
Widget call(EasyDialog dialog) {
  final animation = dialog.context.animation;

  final offset = Tween<Offset>(
    begin: const Offset(0.0, 1.0),
    end: const Offset(0.0, 0.0),
  ).chain(CurveTween(curve: Curves.fastOutSlowIn)).animate(animation);
  return AnimatedBuilder(
    animation: animation,
    builder: (_, __) => Stack(
      children: [
        Positioned.fill(
          child: ColoredBox(
            color: Colors.black.withOpacity(
              animation.value.clamp(0.0, 0.6),
            ),
          ),
        ),
        Align(
          alignment: Alignment.bottomCenter,
          child: SlideTransition(position: offset, child: dialog.content),
        ),
      ],
    ),
  );
}
}
