We can defer these by deferring guards and const instance properties,

writable instance properties usable (with default value undefined)
before being initialized.
Of course, Dart allows this and discloses null on use before initialization:
class Foo {
var a;
Foo(a) {
print(this.a);
this.a = a;
}
}
main() {
var foo = new Foo(42);
print('main: ' + foo.a);
}
