// This is a regression test for dartbug.com/26406. We test that the deferred
// loader analyzer doesn't trip over constant expression evaluation.
//
// Today the task uses constant values to calculate dependencies, and only uses
// those values that were previously computed by resolution. A change to compute
// the value on-demmand made the deferred task evaluate more expressions,
// including expressions with free variables (which can't be evaluated). See the
// dartbug.com/26406 for details on how we plan to make the task more robust.
// import is only used to trigger the deferred task
import 'deferred_class_library.dart' deferred as lib;
class A {
final int x;
const A(bool foo)
// The deferred task would crash trying to compute the value here, where
// [foo] is a free variable.
