Unable to build default value

[molon]

xml_layout/lib/builder/builder.dart

Lines 297 to 299 in 1c6fc36

	if (param.hasDefaultValue) {
	argv.add(param.defaultValueCode!);
	}

TextStyle.inherit AppBar.automaticallyImplyLeading AppBar.primary and so on.

I tried to debug the issue and found ParameterElement.hasDefaultValue is not correct some times.
