Recently started testing different frameworks to build small standalone apps to help manage a bigger (quite large) system. Latest one I was working with was TKinter for python and it was good. Running queries and generating reports. but the UI was very outdated. Yesterday I started looking into flutter for windows desktop and been looking at available packages on pub.dev
It depends on what your needs are. Database drivers for connecting straight into a database server will be limited. Dart just hasn’t gained as much momentum on the server side as other languages and most apps use an n-tier architecture so no need for drivers. There’s no server side rendering for flutter so your app startup time might be a hinderance for a user just wanting to pull up a web page and see some data.
