Futures

Basics

import 'dart:io';

void anotherJob() {
  print('u know stuff and that');
}

Future<int> working() async {
  print('working');
  int a = 0;
  await Future.delayed(Duration(seconds: 2), () {
    print('done');

    a = 1;
  });

  return a;
}

void done(int a) {
  print(a);
}

void main() async {
  working().then((value) {
    done(value);
  });
  anotherJob();
}

await - put this in front of a async function

async - you put this in the function definition

Pass in lambda functions as args into the following for each scenario

final myFuture = Future<int>.delayed(
  Duration(seconds: 1),
  () => 42,
)
    .then(
      (value) => print('Value: $value'),
    )
    .catchError(
      (Object error) => print('Error: $error'),
    )
    .whenComplete(
      () => print('Future is complete'),
    );
