Functions
-
decodePartialNdefMessage(
TypeNameFormat tnf, Uint8List type, Uint8List payload, {Uint8List? id}) → NDEFRecord - Decode a NDEF record, providing its parts separately. This is most useful in mobile environment because the APIs will give you these information in a separate manner.
-
decodeRawNdefMessage(
Uint8List data, {dynamic typeFactory = NDEFRecord.defaultTypeFactory}) → List< NDEFRecord> - Decode raw NDEF messages (containing at least one NDEFRecord) from byte array
-
encodeNdefMessage(
List< NDEFRecord> records, {bool canonicalize = true}) → Uint8List -
Encode an NDEF message (containing several NDEFRecords) to byte array.
Set
canonicalizeto set the MB and ME fields automatically in the first / last record.
Typedefs
- TypeFactory = NDEFRecord Function(TypeNameFormat tnf, String classType)
-
Construct an instance of a specific type (subclass) of NDEFRecord according to
tnfandclassType
