Generic function can't be passed as an argument

This code compiles fine, but the analyser gives an error:
```
The argument type 'List<T> Function<T>(T)' can't be assigned to the parameter type 'List<Z0> Function<F>(F)'. 
```

Code:
```dart
List<T> toList<T>(T x) => [x];

R calc<R>(R Function<F>(F) f) {
  return f(0);
}

void main() {
  final res = calc(toList);
  print(res);
}
```
