invalid warning "bool is not assignable to bool"

void _completeFunction(Function func, Completer compl) {
 if(!compl.future.isComplete) { // here it says () -> bool is not assignable to bool
   compl.complete(func);
 }
}

Works for me, probably because of r7963.

class FFuture {
  bool get isComplete() => false;
}

class Completer2 {
  FFuture get future() {}
  void complete(Function func) {}
}

void _completeFunction(Function func, Completer2 compl) {
  if(!compl.future.isComplete) { // here it says () -> bool is not assignable to bool
    compl.complete(func);
  }
}
