metadata_fetch 0.1.1

A library for fetching metadata from websites. It parses OpenGraph tags first, then parses HTML meta as a fallback.

Metadata Fetch

A dart library for extracing metadata on web pages such as OpenGraph, Meta, and soon, Twitter-Cards and json+LD Schemas.

Usage

Fetch Metadata for a given URL

import 'package:metadata_fetch/metadata_fetch.dart';

main() async {
  var data = await MetadataFetch.getMetadata("https://flutter.dev/");

  print(data['title']) // Flutter - Beautiful native apps in record time
  print(data['description'])
  print(data['image']) // https://flutter.dev/images/flutter-logo-sharing.png
}

Bad URL

import 'package:metadata_fetch/metadata_fetch.dart';

main() async {
  var data = await MetadataFetch.getMetadata("https://broken/");

  print(data) // null

}

Credit

This library is inspired by open_graph_parser. However this one tries to be more general.

Roadmap

• Improve Documentation
• Implement json-ld parser for schema metadata.
