This thing has got an annoying bug as of now, but you just need to use dioxus-cli and pass the --hot-patch flag to it. Still trying to figure out the issue

you need to first use dioxus-cli with my pr that allows using only hot-patching: DioxusLabs/dioxus#4475

and then use this freya in this pr.

to run the app you need to do dx serve --hot-patch --hot-reload false
