Serialising object works fine, deserialising fails

[daveshirman]

Background:

• Got some data from my API
• Checked that data by type casting with my fromJson method, which works
• Then saved to semblast storage.
• Then tried to retrieve that saved object
• Fails on de-serialisation of nested List<String>

Why is it that my map object, which has a nested List<String> property assetSubTypeNames will serialise fine, but when de-serialising, it's not properly done?

The List<String> property assetSubTypeNames should be a Map at this point. Surely?

Please explain what I'm doing wrong. Thanks!

Note:

If I add the following code between lines 52 + 53:

    for (var item in map['assetTypes'] as List) {
      item['assetSubTypeNames'] = jsonDecode(item['assetSubTypeNames']);
    }

it works fine. But I shouldn't have to.

Error

Unhandled Exception: type 'String' is not a subtype of type 'Iterable<dynamic>'

Indeed it seems that assetSubTypeNames is a String not a list since you are encoding it as a string your toJson() method:

'assetsSubTypeNames': jsonEncode(assetSubTypeNames)

My guess is that you should just do:

'assetsSubTypeNames': assetSubTypeNames

You are absolutely correct. My apologies. Thanks!
