Convert Future<int> to int in Flutter

How to convert Future int to int in flutter?

Example: I have a function that return a Future int and I want to compare if the return output is greater than or equal to zero.

Thanks in advance

@marj29 in order to get value out of the Future you have to use async/await.

import 'dart:async';

class A {
  Future<int> getInt() {
    return Future.value(10);
  }
}

class B {
  checkValue() async {
    final val = await A().getInt();
    print(val == 10 ? "yes" : "no");
  }
}

You can find more on that in the dart lang tutorials.

Late but might be useful for others.

suppose you have a function called getCount() that returna a Future value.
simply do this:
int count = await getCount();
now you can use count variable any where needed.
