flutter_share_content

Description:

flutter share content

Share content for flutter #

A simple plugin for Flutter to share content.
This content could be a picture but also a message. Furthermore a title can be added to show in the sharing screen.
Every version of Android is supported, included from version 24 and above.
For those devices is mandatory the use of FileProvider class in order to grant access
to the images stored in the phone.
Version 0.2.0 is supporting androidX.
iOS is not going to be implemented because I don't have a macOS.
