Sometimes we may want to control our app execution to pause it for performing multiple tasks depending on our needs. In this article, we will see different ways to sleep our flutter app execution.
Timer Class
The Timer class can be used to run the code after a specific time because it has a duration property that can help us to sleep our app.
Example using Timer Class
Timer(Duration(seconds: 2), () {
// our code here
});In the above example, the Timer constructor accepts two arguments the first one is duration which we set to 2 seconds and the second one is an anonymous function that can be used to execute our code. So after 2 seconds of sleep, our code will be executed.
Future.delayed
The Future class has a delayed method that can be used to sleep our app.
Example using Future.delayed
Future.delayed(Duration(seconds: 3), () {
// our code here
});In the above example, the delayed method accepts two arguments the first one is duration which we set to 3 seconds and the
second one is the anonymous function which can be used to execute our code. So after 3 seconds of sleep, our code will be executed.
Sleep Method
The sleep method can also be used to pause our app execution.
Example using Sleep Method
Import the library
import 'dart:io';Then we can use the sleep method
sleep(2000);In the above example, the sleep method from the dart:io library accepts one argument which we passed as 2000. So after 2 seconds of sleep, our code will be executed.
Conclusion
We discussed the 3 ways to sleep in our app, you can use the one that best satisfies your need.
