title: Restart CircularCountdownTimer flutter onComplete
body: <p>Hey im trying to have a CircularCountDownTimer restarting every time it finishes counting to 60,</p>
  <p>I was hoping it has to do with onComplete(), but I can't figure out how to restart it.</p>
  <p>any help appreciated, thanks.<br />
  this is the CircularTimer widget:</p>
  <pre><code>                        CircularCountDownTimer(
  
                            duration: 60,
                            width: MediaQuery.of(context).size.width,
                            height: MediaQuery.of(context).size.height,
                            color: Colors.grey[300],
                            fillColor: Colors.yellow[800],
                            strokeWidth: 4.0,
                            textStyle: TextStyle(
                                fontSize: 0.0,
                                color: Colors.black87,
                                fontWeight: FontWeight.bold),
  
                            isReverse: false,
  
                            
                            onComplete: () {
  
                              setState(() {
                                min --;
                              });
                              
                            },
                          )
  </code></pre>
