A simple library parsing the open graph data of a given URL.
Usage example:
var data = await OpenGraphParser.getOpenGraphData("https://share.jodel.com/post?postId=5bbf7b84ee274646a2d96147&_branch_match_id=536882993144588943")
print(data['image']);Result is: http://img.jodel.com/5bbf7b84ee274646a2d96147_pp4ELmdCl0PbKDNF_image.jpeg
Required values are at this moment title and image.
If they are not present, this library tries to create a fallback using the title tag in head and the first image it can find in the body.
