Creating a Flet application with a custom template

[ap4499]

Question

Objective: Create a Flet application with a custom template that can be packaged using Flet Pack.

Reasons:

• Flet build isn't used as I can't get multiprocessing to work.
• I need a custom template, as on the MacOS build, I need to change the default icon to a custom one.
• When running the application on MacOS, even after stipulating the icon, the OS will show the Flet icon due to the template (when using Flet Pack).

Questions:

• What is the best way of setting up a custom template, with the very minor modification of an altered icon?
• How can I ensure that when using Flet Pack, the custom template is picked up?

Other thoughts:

• I have come across Flet Create command. Would it be as simple as find/replace on the icon.png files from the template file (https://github.com/flet-dev/flet-app-templates), and then referencing that version?
• I already have a substantial amount of Flet code, around 4k lines - so I can't really start entirely from scratch.
