I have started playing with flutter, specifically flutterflow.io. It’s a site where using tools that remind me of an android widget maker on steroids, you build an app visually and it converts it to flutter. (It also compiles it for iOS and android and sends it to the stores automatically).
I linked it to my GitHub account and I have been pushing versions of a very silly app there. Then I download it, make changes, and play with it. I even set up a Jenkins process to build a web version of the app and put it on a web server.
I also built a dotnet backend to provide an api layer. Some really lame code so far, but the cool part is that I do all the work on a Mac and compile it on a raspberry pi where it’s served by apache. And it still works and is fast. I also did a bit of an overkill, spun up an instance of Maria in a container, and set up the dotnet website to store session state in the database. (I am serving the dotnet through apache via mod_proxy. Apache is also handling the cors signature, although I handle the options calls through the Kestrel pipeline.
