[Formatting issue] trailing_commas=preserve not working for some enums with a constructor declaration #1729
Description
When setting trailing_commas to preserve, I would expect the formatter to preserve trailing commas in my code. This is not the case when creating an enum with a constructor as shown below.
What input code did you provide to the formatter?
enum RawPhotoType {
jpeg('image/jpeg'), png('image/png'),
;
final String mimeType;
const RawPhotoType(this.mimeType);
}What output did the formatter produce?
enum RawPhotoType {
jpeg('image/jpeg'),
png('image/png');
final String mimeType;
const RawPhotoType(this.mimeType);
}What output did you expect or want the formatter to produce?
enum RawPhotoType {
jpeg('image/jpeg'),
png('image/png'),
;
final String mimeType;
const RawPhotoType(this.mimeType);
}
