NitroWireCodec<T extends Object> class abstract

Platform-neutral codec for a @NitroCustomType T transported across the bridge as an optional fixed-size value: [1B hasValue][encodedSize-1 bytes].

This is the byte-level counterpart of the native-only NitroFfiCodec<T> (which speaks Pointer<Uint8>): the same wire layout expressed over ByteData, so one codec implementation works on native AND web.

Web-targeting specs with @NitroCustomType must provide a NitroWireCodec; native-only specs may keep using NitroFfiCodec.

Example:

class ColorWireCodec extends NitroWireCodec<Color> {
  const ColorWireCodec();
  @override int get encodedSize => 5;   // 1B flag + 4B RGBA

  @override void write(ByteData out, int offset, Color? v) {
    out.setUint8(offset, v != null ? 1 : 0);
    if (v != null) { out.setUint8(offset + 1, v.r); /* ... */ }
  }

  @override Color? read(ByteData bytes, int offset) {
    if (bytes.getUint8(offset) == 0) return null;
    return Color(bytes.getUint8(offset + 1), /* ... */);
  }
}
