    TutorialCoachMark tutorial = TutorialCoachMark(
      targets: targets, // List<TargetFocus>
      colorShadow: Colors.red, // DEFAULT Colors.black
       // alignSkip: Alignment.bottomRight,
       // textSkip: "SKIP",
       // paddingFocus: 10,
       // focusAnimationDuration: Duration(milliseconds: 500),
       // unFocusAnimationDuration: Duration(milliseconds: 500),
       // pulseAnimationDuration: Duration(milliseconds: 500),
       // pulseVariation: Tween(begin: 1.0, end: 0.99),
       // showSkipInLastTarget: true,
       // imageFilter: ImageFilter.blur(sigmaX: 8, sigmaY: 8),
       // initialFocus: 0,
       // useSafeArea: true,
      onFinish: (){
        print("finish");
      },
      onClickTargetWithTapPosition: (target, tapDetails) {
        print("target: $target");
        print("clicked at position local: ${tapDetails.localPosition} - global: ${tapDetails.globalPosition}");
      },
      onClickTarget: (target){
        print(target);
      },
      onSkip: (){
        print("skip");
      }
    )..show(context:context);

    // tutorial.skip();
    // tutorial.finish();
    // tutorial.next(); // call next target programmatically
    // tutorial.previous(); // call previous target programmatically
    // tutorial.goTo(3); // call target programmatically by index
  }

Creating targets (TargetFocus)

TargetFocus is the class that represents the widget that will be focused and configure what will be displayed after you focus it.

Attributes:

Attribute	Type	Description
`identify`	dynamic	free for identification use
`keyTarget`	GlobalKey	GlobalKey widget that wants to be focused
`targetPosition`	TargetPosition	If you do not want to use GlobalKey, you can create a TargetPosition to determine where to focus
`contents`	ContentTarget[]	Content list you want to display after focusing widget
`shape`	ShapeLightFocus	ShapeLightFocus.Circle or ShapeLightFocus.RRect
`radius`	double	Use when shape = ShapeLightFocus.RRect
`borderSide`	BorderSide
`color`	Color	Custom color to target
`enableOverlayTab`	bool	enable click in all screen to call next step
`enableTargetTab`	bool	enable click in target to call next step
`alignSkip`	Alignment	use to align the skip in the target
`paddingFocus`	Alignment	settings padding of the focus in target
`focusAnimationDuration`	Duration	override the widget's global focus animation duration
`unFocusAnimationDuration`	Duration	override the widget's global unfocus animation duration
`pulseVariation`	Tween	override interval pulse animation

Creating contents (ContentTarget)

ContentTarget is the class responsible for determining what should be displayed and how it will appear after focusing on the widget.
