@srawlins The commit you mention has 2.16.0-xx labels, I'm assuming that means it is fixed in Dart 2.16.0. But I still see the issue with Dart 2.16.1. I managed to narrow it down to the code that causes the issue (edit: I see that this is basically what you already mentioned). In this example, uncommenting the class Foo {
/* const */ Foo.bar() : this(const _Dummy());
const Foo(this.foo);
final void Function(bool) foo;
}
class _Dummy {
const _Dummy();
void call(bool x) {}
}Perhaps related, if I add: void fun() {
const x = Foo(_Dummy()); // *

After increasing the minimum SDK constraint of our packages to 2.15, the analysis server crashes after a while. Breaking syntax highlighting, code completion, etc. Things worked fine when the constraint was still
>=2.12in our pubspec.yaml files and>=2.14.0in pubspec.lock files due to some dependency that required it (but using Flutter 2.8/Dart 2.15).Dart analysis issue
