Json_serializable.dart: How to handle Uint8List type ?

[benoitverstraete]

Hi,

I try to use the json_serializable package to convert Uint8List (byte[]) in JSON but I have this error message :

Error running JsonSerializableGenerator
Could not generate fromJson code for imageContent.
None of the provided TypeHelper instances support the defined type.
╷
27 │ Uint8List imageContent;
│ ^^^^^^^^^^^^
╵

Here is the source code :

@JsonKey(name: 'image_content')
Uint8List imageContent;

Could you please tell me how to handle the Uint8List type with your package ?

Thanks a lot

You'll have to add a converter for this.

See https://github.com/dart-lang/json_serializable/blob/master/example/lib/json_converter_example.dart#L33

I'm likely NOT going to add support for these types.
