dcall(f, args, [@undefined named]) => _checkAndCall(
    f, null, JS('', 'void 0'), null, args, named, JS('', 'f.name'));

dgcall(f, typeArgs, args, [@undefined named]) => _checkAndCall(f, null,
    JS('', 'void 0'), typeArgs, args, named, JS('', "f.name || 'call'"));

Both of these methods attempt to pass f.name as the displayName argument to _checkAndCall(). When f is null the error messages are misleading and the code in _checkAndCall() meant to handle null and provide a more helpful error message is not being executed.

ex:

We should add additional test cases to https://github.com/dart-lang/sdk/blob/7e86f2e71cdfa17761ae418ae471f49fb0b72269/tests/dartdevc/no_such_method_errors_test.dart
