registerHeadlessSyncBodyBuilder abstract method

Future<bool> registerHeadlessSyncBodyBuilder(
  1. Future<JsonMap> builder(
    1. SyncBodyContext context
    )
)

Registers a headless-compatible sync body builder.

The callback must be a top-level or static function (not a closure) to work in headless/terminated mode.

  Future<JsonMap> Function(SyncBodyContext context) builder,
);
