BufferedOutputStream constructor

Creates a new buffered output stream to write data to the specified underlying output stream.

Parameters

• output: The underlying output stream
• bufferSize: The buffer size (default: 8192 bytes)

Example

final buffered = BufferedOutputStream(FileOutputStream('output.bin'));
final largeBuffered = BufferedOutputStream(
  FileOutputStream('huge_output.bin'), 
  bufferSize: 65536
);

The class implements a buffered output stream.

By setting up such an output stream, an application can write bytes to the underlying output stream without necessarily causing a call to the underlying system for each byte written.

Example Usage

// Basic buffered writing
final buffered = BufferedOutputStream(FileOutputStream('output.bin'));
try {
  for (int i = 0; i < 10000; i++) {
    await buffered.writeByte(i % 256);
  }
  await buffered.flush(); // Ensure all data is written
} finally {
  await buffered.close();
}

// Writing large amounts of data efficiently
final buffered = BufferedOutputStream(
  FileOutputStream('large_output.bin'),
  bufferSize: 65536 // 64KB buffer
);
try {
  final data = generateLargeDataSet();
  await buffered.write(data);
  await buffered.flush();
} finally {
  await buffered.close();
}
