飞镖/颤振每次之后如何定期更改计时器 [英] Dart/flutter how to change the timer inside periodic after every time

问题描述

我正在为在我的应用中展示广告制定自定义逻辑，因此，当用户在弹出1分钟后弹出广告时打开应用，然后假设这1分钟每次都会增加1分钟，因此x为2 3然后4 ...等等。

I'm making a custom logic for showing ads in my app, so when the user opens the app after 1 min pops up an ad then supposed this 1 min to get increased by 1 min every time, So x be 2 then 3 then 4 ...etc.

我尝试这样做，但对我没有用（每隔1分钟显示一次广告就不会增加）；

I tried to do so, but didn't work for me ( showing the ad every 1 min not increase it );

int x = 1;
Timer.periodic(Duration(minutes: x), (timer) { 
  x = x + 1;
  interstitialAd.load();
});

推荐答案

我认为您无法做到。您也可以根据情况取消当前计时器并启动新计时器。检查以下伪代码

I think you cannot do it. You can alternatively cancel the current timer and start a new timer based on conditions. Check the following pseudo-code

  Timer.periodic(Duration(minutes: 5), (timer) {
      if(condition){
        timer.cancel();
        createNewPeriodicTask();
      }
      // task code
  });
