What is a future data type in Flutter

Question

Hi Guys,

I am new in Flutter. I want to create one asynchronous function using future data types in Flutter. How can I do that?

Hi@akhtar,

Future is a type that ‘comes from the future’ and returns a value from your asynchronous function. It can complete with success or with an error. You can also see the below-given example.

void main() async {
  await waitForMe();
  print('I was waiting here :)');
}Future waitForMe() async {
  print('Started.');
  return Future.delayed(Duration(seconds: 5), () {
    print("Now I'm done!");
  });
}
