Dartc: Default class without constructor does not cause a compile-time error #985
Description
This issue was originally filed by [email protected]
In the section 7.5 the specification says: "If no constructor is specified for a class C, it implicitly has a default constructor C() : super() {}, unless it is class Object."
In the section 8.3: "A constructor kI of I corresponds to a constructor kF of its factory class F if either F does not implement I and kI and kF have the same name, OR ... It is a compile-time error if an interface I declares a constructor kI and there is no constructor kF in the factory class F such that kI corresponds to kF ."
The test is following:
class F {
}
interface I default F {
I();
}
main() {
new I();
}
According to the specification, there is implicit constructor F():super() {} in the class F. But this is not the constructor to which constructor I() corresponds. So, a compile-time error have to occur. But dartc(r2810) does not produce it.
