pushSampleSync method

int pushSampleSync(
  1. List data
)

Synchronously pushes a sample to the outlet.

Direct mode only - throws LSLException if useIsolates: true.

This provides maximum timing precision by eliminating all async overhead. Ideal for high-frequency data streaming or when precise timing is critical.

Example:

final outlet = await LSL.createOutlet(streamInfo: info, useIsolates: false);

// High-precision sampling loop
while (streaming) {
  final data = generateSample();
  outlet.pushSampleSync(data); // Zero async overhead
}

Returns: Error code (0 = success). See also: pushSample for async operations Throws: LSLException if useIsolates: true or data validation fails.

Implementation

int pushSampleSync(List<dynamic> data) =>
    requireDirect(() => _pushSampleDirect(data));
