FileReader class

Convenience class for reading character files.

The constructors of this class assume that the default character encoding and the default byte-buffer size are appropriate. To specify these values yourself, construct an InputStreamReader on a FileInputStream.

FileReader is meant for reading streams of characters. For reading streams of raw bytes, consider using FileInputStream.

Example Usage

// Reading a text file
final reader = FileReader('document.txt');
try {
  final content = await reader.readAll();
  print('Document content: $content');
} finally {
  await reader.close();
}

// Reading line by line
final reader = FileReader('data.txt');
try {
  String? line;
  int lineNumber = 1;
  while ((line = await reader.readLine()) != null) {
    print('Line $lineNumber: $line');
    lineNumber++;
  }
} finally {
  await reader.close();
}
