Flutter restart countdown timer-CodePudding

I'm trying to restart the countdown timer when I click on the resend code. The package I'm using is timer_count_down.

I've tried adding:

 onTap: () {
     _controller.restart();
     _submit();
 },

But it can't seem to work. here is my code:

final CountdownController _controller =
  new CountdownController(autoStart: true);

@override
  Widget build(BuildContext context) {
    return Countdown(
            seconds: 40,
            build: (_, double time) =>
                Column(
                  children: [
                    Text(time.toString(),
                      style: TextStyle(
                        color: Theme.of(context).primaryColor,
                      ),
                    ),
                    SizedBox(height: 30,),
                    Visibility(
                      visible: time == 0,
                      child: Column(
                        children: [
                          Text('Haven\'t recieved the code?',
                            style: TextStyle(
                              color: Colors.grey
                            ),
                          ),
                          SizedBox(height: 10,),
                          InkWell(
                            onTap: () {
                              _controller.restart();
                              _submit();
                            },
                            child: Text('Resend code',
                            style: TextStyle(
                              color: Theme.of(context).primaryColor,
                              fontWeight: FontWeight.bold,
                              decoration: TextDecoration.underline,
                            ),),
                          ),
                        ],
                      ))
                  ],
                ),
          ),

Is there any solutions to this?

CodePudding user response：

I've been able to reproduce your issue both by using your provided code and the example code of the package (provided by the project) github.com/DizoftTeam/simple_count_down/blob/master/example/lib/main.dart.

This issue is in both cases caused by not having the CountdownController assigned to the Countdown widget.

You should add the following line of code to the Countdown widget: controller: _controller,

It should look like this:

return Countdown(
        controller: _controller,
        seconds: 40,

Add a interval property

interval: Duration(milliseconds: 100),

and after try to restart

 onTap:: () {
   _controller.restart();
 },
