Cordova saveImageGallery Plugin
Updated to work for Android 10+ without needing permissions.
This plugin (based on devgeeks/Canvas2ImagePlugin) allows you to save base64 data as a png/jpg image into the device (iOS Photo Library, Android Gallery or WindowsPhone 8 Photo Album).
The plugin is a kind of fork of the Nexxa/cordova-base64-to-gallery/ but with a cleaner history and some extra features - like supporting saving into JPG, sending parameters in an easier way, etc.
