how to generat or create "appcastURL" for upgrader package in flutter?
I found another package called new_version its very simple and clear, no need to any extra steps or customizations.
Create a new file appcast.xml
Paste this in it
<?xml version="1.0" encoding="utf-8"?><rss version="2.0" xmlns:sparkle="http://www.andymatuschak.org/xml-namespaces/sparkle"> <channel> <title>Help Code TJCODE- Appcast</title> <item> <title>Version 1.15.0</title> <description>desc</description> <pubDate>Tue, 08 Jun 2021 12:00:00 +0000</pubDate> <enclosure url="https://play.google.com/store/apps/details?id=com.example.app" sparkle:version="1.0.0" sparkle:os="android" /> </item> </channel></rss>Edit the details in this file to suite your own app config.
