Getting values from Future instances

Question

My data is something like this:

{
  \"five\": {
    \"group\": {
      \"one\": {
        \"order\": 2
      },
      \"six\": {
        \"order\": 1
      }         


        

Answer 1

There is no way to get back from async execution to sync execution.

To get a value from a Future there are two ways

pass a callback to then(...)

theFuture.then((val) {
  print(val);
});

or use async/await for nicer syntax

Future foo() async {
  var val = await theFuture;
  print(val);
}
