Notes

• Native developers who can help me in implementing native methods for fetching meta data are most welcome, which might give us promising results for all sort of public url's.
• Do you have any suggestions in improving the Package/Plugin? I really love to do this kind of stuff. Do contact me here.
• If you have used this package in your application, drop a smile & your app link to me, I will be adding those to the same page.
