toJson method
Serializes the part to a JSON map.
The returned map must contain a key matching typeKey with a unique string identifier for the part type. See defaultPartConverterRegistry for default part types.
Implementation
@override
Map<String, Object?> toJson() => {
Part.typeKey: type,
_Json.content: {
if (name != null) _Json.name: name,
_Json.mimeType: mimeType,
_Json.bytes: 'data:$mimeType;base64,${base64Encode(bytes)}',
},
};
