  LockView({
        this.width,                                                        //Width
        this.height,                                                       //Height
        this.password,                                                     //Password ex,[0,1,2,4,6,7,8] for Z pattern
        this.gridNumber = 3,                                               //GridNumber Default 3 means 3x3
        this.lineWidth = 5,                                                //Width Of Follow-Line                                                     
        this.circleRadius = 0.15,                                          //Radius Of Circles
        this.borderColor = Colors.black,                                   //BorderColor Of Circle
        this.normalColor = Colors.white,                                   //NormalColor Of Circle
        this.correctColor = Colors.green,                                  //Color When Unlocked
        this.incorrectColor = Colors.red,                                  //Color When Wrong Guess
        this.passColor = Colors.blue,                                      //Color When Circles Selected
        this.background = const BoxDecoration(                             //Background Decoration
              color: Colors.white, 
              boxShadow: [BoxShadow(blurRadius: 10)],
              borderRadius: BorderRadius.all(Radius.circular(20))),
        this.lineDecoration=const BoxDecoration(                            //Line Decoration
              color: Colors.grey,
              boxShadow: [BoxShadow(blurRadius: 10)]),
        this.onEndPattern,                                                  //Called When DragEnd
        this.takePattern = false,                                           //Want To Take Pattern Instead?
        this.onEndTakePattern                                               //Called When DragEnd and takePattern=true
      });

Note: When takePattern = true, LockView Will Not Be Cleared After DragEnd, For Clear It, Change It By Parent SetState((){}) Callback.

Example #

class _HomeState extends State<Home> {
  bool unlock = false;
  @override
  Widget build(BuildContext context) {

    return Scaffold(
      appBar: AppBar(title: Text("LockView Example"),),
      body: Center(
        child:
          Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
            Padding(padding: EdgeInsets.only(bottom: 30),child: SizedBox(height: 50,child: FittedBox(child: Text(unlock?"UnLocked":"Locked")))),
            
            LockView(
                  height: 300,
                  width: 300,
                  password: [0,1,2,4,6,7,8],
                  onEndPattern: (didUnlocked) {
                        setState(() {
                          unlock = didUnlocked;
                        });
                         if(didUnlocked){
                         Navigator.push(context, MaterialPageRoute(builder: (c)=>Scaffold(
                              appBar: AppBar(title: Text("Unlocked Content"),),
                              body: Center(child: Text("Unlocked",style: TextStyle(fontSize: 30),),),)));
                    }
                  },
            )],
          )
      )
    );
  }
