[dart-misc] Function annotation for field as a class

['Karan Sikka' via Dart Misc]

Hi, I can't find how to properly annotate a function that's a field as a
class.

Say I have

class Configuration {
Function statsGetter;
Configuration(this.statsGetter);
}

Any way I can further annotate Function statsGetter to have input/output
type annotations?

This was just added to the language in 1.24.0:

https://github.com/dart-lang/sdk/blob/master/CHANGELOG.md#1240---12-06-2017

typedef F = void Function(); // F is the name for a `void` callback.
int Function(int) f; // A field `f` that contains an int->int function.

class A<T> {
// The parameter `callback` is a function that takes a `T` and returns
// `void`.
void forEach(void Function(T) callback);
}

// The new function type supports generic arguments.
typedef Invoker = T Function<T>(T Function() callback);
