readByteSync method

@override int readByteSync()

Reads a single byte synchronously from input.

This is the primary method used for key event reading. Blocks until a byte is available.

Implementation

@override
int readByteSync() {
  if (_byteQueue.isEmpty) {
    throw StateError('MockTerminalInput: No bytes queued for readByteSync');
  }
  return _byteQueue.removeAt(0);
}
