crawler_detector

Description:

crawler detector

Helps Flutter and Dart apps detect when they are being crawled by a web crawler.
Features #
This package pattern-matches the user agent string against a list of known
patterns to detect a crawler.
The implementation can detect crawlers in all Dart web targets, including
Flutter Web apps, and DOM-based Dart
apps (e.g. those using Jaspr or
AngularDart).
Dart VM targets are not web targets, and therefore you can never detect a
crawler from within the Dart VM (e.g. command-line Dart apps, Flutter mobile or
desktop apps).
Usage #
Add a dependency to pubspec.yaml:
dependencies:
crawler_detector: any

}
