PrefCodec class
Encodes and decodes tagged preference values.
Layout is [tag u8][payload…]:
string— UTF-8 bytesint64— 8 bytes, little-endian two's complementfloat64— 8 bytes, little-endian IEEE-754boolean— 1 byte,0or1stringList—[count u32][len u32][utf8]…, all little-endianbytes— verbatim
Fixed-width integers keep decoding allocation-free, and every length is bounds-checked against the buffer before it is used to slice.

encodeInt(
int v) → Uint8List - Encodes a 64-bit signed integer.
-
encodeString(
String v) → Uint8List - Encodes a UTF-8 string.
-
encodeStringList(
List< String> v) → Uint8List - Encodes a list of strings.
-
expect(
String key, Uint8List raw, PrefType want) → void -
Verifies the tag matches
want, throwing PhoenixTypeMismatch if not. -
typeOf(
String key, Uint8List raw) → PrefType - Reads the type tag, or throws when the buffer is empty or unknown.
