[Dot Shorthands] `non_constant_default_value`

[RohitSaily]

Dart SDK version: 3.9.0-235.0.dev (dev) (Fri Jun 13 21:03:03 2025 -0700) on "macos_x64"

Consider

class T
{	const T();
}
void f([T t=T()]) // ERROR: non_constant_default_value
	{}

non_constant_default_value is reported as expected and can be resolved by changing [T t=T()] to [T t=const T()]. But if the experimental dot shorthand syntax is used to invoke the same constructor without the const keyword, no error is reported by the static analyzer via VSCode

void f([T t=.new()]) // no error :(
	{}

The error is only reported when trying to run the code
