NitroTuple class

Marks a Dart 3 positional record typedef as a named tuple type.

Annotate a typedef whose aliased type is a Dart 3 positional record (T1, T2, ...). The generator emits encode/decode helpers that bridge the positional record across the C FFI boundary using the same binary codec as @HybridRecord — sequential field writes with a 4-byte length prefix. Fields are accessed via $1, $2, ... on the Dart side.

Wire format: [4B len][field1 bytes][field2 bytes]... (same as @HybridRecord)

Dart: (T1, T2, ...) positional record C: uint8_t* (same as @HybridRecord) Kotlin: data class Name(val field0: T0, val field1: T1, ...) Swift: struct Name { var field0: T0; var field1: T1; ... }

Example:

@NitroTuple()
typedef MyPair = (int, String);

@NitroModule(...)
abstract class Counter {
  MyPair getPair();
  void setPair(MyPair v);
}
