Thanks for your time and thoughts! If I stay with traditional web stuff I will most like go with Vue. I enjoyed using it! I could stay with Python (I enjoy using it) and then I would use Django or Flask - I have used both with success. So why am I considering using flutter?

The client has had a very long history of avoiding using the web. Putting something in the cloud worries them very much. Even today they use very little web. The office uses local lan and the remotes use RDP to run the programs. This program has been running 12 years and there have been so many business changes and I have hacked the code so many times that it is time to rewrite. So the question is how can I lower the cost and speed up the delivery of the product to my client.

If I put everything in the cloud (my client does not like the idea) then when the internet goes down the remotes will still work but the office will not. If I install on the local lan then the remotes do not work when the internet is down (that is how it works currently). And does it take less time to deliver a Flutter app (like FoxPro took less time over other tech). Google has just delivered a new OS. It will run Flutter apps. That might mean the client can just run the new OS on chromebooks, and old computers without the need to spend on new computers. So you see those reasons are why I decided to ask you folks.
