Starting Code for Futures/Async/Await Demo

scratch.dart

import 'dart:io';

void main() {
  performTasks();
}

void performTasks()  {
   task1();
   task2();
   task3();
}

void task1() {
  String result = 'task 1 data';
  print('Task 1 complete');
}

void task2()  {
 String result = 'task 2 data';
  print('Task 2 complete');
}

void task3() {
 String result = 'task 3 data';
  print('Task 3 complete');
}

For VS Code user, you can run this scratch file by running dart scratch.dart in Terminal.

Result:

PS C:\Users\maple\Documents\Flutter course App Brewery\Learn-Flutter-AppBrewery\Section 13 Clima\Clima-Flutter> dart scratch.dart  
Task 1 complete
Task 2 complete
Task 3 complete
PS C:\Users\maple\Documents\Flutter course App Brewery\Learn-Flutter-AppBrewery\Section 13 Clima\Clima-Flutter>

In VS Code, you can also get the Code Runner extension by Jun Han which will let you right-click on the scratch.dart file and click "Run Code" to achieve the same thing.

really a good teaching method

same , i have use it for run ios/android/only single file .dart . flutter2.2_scratch_completed.dart

good good study
day day up!

good and nice try..

the course is outdated it is taking lot of time to debugging null safety

this course needs updates and re-shaping

not working because of null safety

just need to add : late on

Future task2() async {
Duration threeSeconds = Duration(seconds: 3);
late String result;

await Future.delayed(threeSeconds, () {
result = 'task 2 data';
print('Task 2 complete');
});
return result;
}

result =
Task 1 complete
Task 2 complete
Task 3 complete with task 2 data

Process finished with exit code 0
