Answers for "flutter timeout"

flutter delay a function

Future.delayed(const Duration(milliseconds: 500), () {

// Here you can write your code

  setState(() {
    // Here you can write your code for open new view
  });

});

settimeout dart

In addition to Timer mentioned by Chris, there is a Future-based API:

var future = new Future.delayed(const Duration(milliseconds: 10), doStuffCallback);
There is not yet direct support for cancelling a Future callback, but this works pretty well:

var future = new Future.delayed(const Duration(milliseconds: 10));
var subscription = future.asStream().listen(doStuffCallback);
// ...
subscription.cancel();
Hopefully, there will soon be a Stream version of Timer.repeating as well.
