void showTutorial() {
    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");
        return true;
      }
    )..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

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.
