Sharing FaceBook feed #
Sharing Facebook feed requires available internet connection, nothing will happen if not.
You can use internet_connection_checker library. It checks exactly if internet access is available.
Example
if(await InternetConnectionChecker().hasConnection) {
MdInstaFbShare.shareFBFeed(file.path);
}else{
<!--your actions-->
}
