      controller.startTimer();
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: OtpTimerButton(
          controller: controller,

          text: Text('Resend OTP'),
