How do you serialize/parse a nested JSON array in Flutter/Dart if it has no name/key

After decoding, notes is a member of some Map<String, dynamic> as usual. Let's call that m.

So m['notes'] is a list, who's first member, m['notes'][0] is also a list. Its first member, m['notes'][0][0] is another Map<String, dynamic>, which is what you need for your constructor.

You should therefore be able to use:

Note n = Note.fromJson(m['notes'][0][0]);

Let's take the case of you saving automaticNote;

automaticNote = json['notes'][0][0]['automaticNote'];

This offers the key for notes which has an array where your data is at the first point or index 0 (of notes hence [0]) and within that array there is another array which has your data. Again it's the first array item so, [0] and then you're finally at the level with your data so you then use your key for automaticNote, ['automaticNote'].

Note.fromJson(Map<String, dynamic> json) {    automaticNote = json[0][0]['automaticNote'];    contactId = json[0][0]['contactId'];    caseFileId = json[0][0]['caseFileId'];    dateCreated = json[0][0]['dateCreated'];    deletedTime = json[0][0]['deletedTime'];  }
