Description

This pull request introduces support for styling widgets during the Tap Down and Tap Up events by incorporating these concepts as events in the press context variant.

Style(
  $box.height(100),
  $box.width(100),
  $box.color.red(),
  $box.wrap.scale(1),
  $on.press.event(
    (e) {
      switch (e) {
        case PressEvent.onTapUp:
        case PressEvent.onTapDown:
          return Style(
            $box.color.purple(),
            $box.wrap.scale(1),
          );
        case PressEvent.idle:
          break;
      }
      return Style(
        $box.color.blue(),
      );
    },
)

Changes

The main components of these changes are the PressEvent (enum) and the PressEventMixWidgetState (inherited widget). The enum value is held by PressEventMixWidgetState and is updated each time an onTap event occurs.
