// when the death is expected to be caused by a DCHECK. Contrary to
// EXPECT/ASSERT_DEBUG_DEATH however, it doesn't execute the statement in non-
// dcheck builds as DCHECKs are intended to catch things that should never
// happen and as such executing the statement results in undefined behavior
// (|statement| is compiled in unsupported configurations nonetheless).
// Death tests misbehave on Android.
// TODO(gw280): once https://github.com/flutter/flutter/issues/78491 is resolved
// we can potentially remove the condition on NDEBUG here.
