registerHeadlessSyncBodyBuilder method

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

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.

Example:

@pragma('vm:entry-point')
Future<JsonMap> buildSyncBody(SyncBodyContext context) async {
  return {
    'locations': context.locations.map((l) => l.toJson()).toList(),
  };
}

Locus.registerHeadlessSyncBodyBuilder(buildSyncBody);

Implementation

@override
Future<bool> registerHeadlessSyncBodyBuilder(
  Future<JsonMap> Function(SyncBodyContext context) builder,
) async {
  _methodCalls.add('registerHeadlessSyncBodyBuilder');
  return true;
}
