Abstract factory not linked #2008
Description
I have two classes: NoteTime (abstract), and Note, which has a final NoteTime time property.
The Note constructor looks like this:
/// Returns a new [Note] from a JSON object.
///
/// Uses `json ["message"]` for the message and passes `json["time"]` to [NoteTime.fromJson]
factory Note.fromJson(Map<String, dynamic> json) => Note (
message: json ["message"],
time: NoteTime.fromJson(json ["time"]),
);Clicking on NoteTime.fromJson in the docs leads back to the Note constructor... any clue why?
Here's my NoteTime.fromJson:
/// Initializes a new instace from JSON.
///
/// Mainly looks at `json ["type"]` to choose which type of
/// [NoteTime] it should instantiate, and then leaves the
/// work to that subclasses `.fromJson` method.
///
/// Example JSON:
/// ```
/// {
/// "type": "period",
/// "repeats": false,
/// "period": "9",
/// "letter": "M",
/// }
/// ```
factory NoteTime.fromJson(Map<String, dynamic> json) {
switch (stringToNoteTime [json ["type"]]) {
case NoteTimeType.period: return PeriodNoteTime.fromJson(json);
case NoteTimeType.subject: return SubjectNoteTime.fromJson(json);
default: throw JsonUnsupportedObjectError(
json,
cause: "Invalid time for note: $json"
);
}
}
