improve: add `preResolve` parameter for `Named` attribute

`Current`

```dart
@preResolve
@Named('applicationDocumentsDirectory')
Future<String> getVar() => path.getApplicationDocumentsDirectory();
```

`Expected`

```dart
@Named('applicationDocumentsDirectory', preResolve: true)
Future<String> getVar() => path.getApplicationDocumentsDirectory();
```
