OPopupTrigger class Null safety

It simplifies the process of creating a widget which triggers popup.

If you want to fully customize (for example size, alignment) content of a popup, skip popupHeader and popupActionRow fields and set your own widget to popupContent field. Typical usage is as follows:

OPopupTrigger(
   barrierDismissible: false, // by default barrier is dismissible, you can change it though
   barrierColor: Colors.black.withOpacity(0.1), // control over color and opacity of a barrier
   barrierAnimationDuration: const Duration(milliseconds: 150), // control over barrier animation
   triggerWidget: Text('Some text'), // or any [Widget]
   popupHeader: OPopupContent.standardizedHeader('Header text here'), // or any [Widget]
   popupContent: OPopupContent.standardizedText( // or any [Widget]
     'Some content',
   ),
   popupActionRow: Row( // or any [Widget]
     mainAxisAlignment: MainAxisAlignment.spaceAround,
     children: [
       OutlineButton(
         textColor: Colors.white,
         child: Text('Yes'),
         onPressed: () => Navigator.of(context).pop(),
       ),
       OutlineButton(
         textColor: Colors.white,
         child: Text('No'),
         onPressed: () => Navigator.of(context).pop(),
       ),
     ],
   ),
);
