The most common way to use this library to stream log files is by handling the data that is emitted
by tailing a file:
import 'dart:convert' show LineSplitter, utf8;
import 'dart:io' show File, stderr, stdout;

import 'package:file_tailer/file_tailer.dart' show tailFile;

void main(List<String> arguments) {
if (arguments.length != 1) {
stderr.write('You need to provide exactly one file to be tailed.\n');
return 1;
}
final (stream, _) = tailFile(File(arguments.first));
stream
.transform(utf8.decoder)
.transform(const LineSplitter())
.forEach((line) async => stdout.write('$line\n'));
}
