Custom Flutter component with build for web

[aistrych]

For v0.25.2

Creating custom Flutter component according to this docs: https://flet.dev/docs/extend/integrating-existing-flutter-packages/
is not working. After successful build (flet build web) I've got build/web directory that I set in FLET_WEB_PATH env. Next I try to run my app with uvicorn like that:

uvicorn main:app --host 127.0.0.1 --port 8888 --reload

but it is not working: nothing is displayed on canvas and there is no error regarding unknown control. Without exporting FLET_WEB_PATH before that such text is visible.
Also it looks like what is served in build/web directory is a standalone version where python code is interpreted by pyodide and I would like to have client server version.

Yes, the result built with flet build web is a static website. If you want to use web part with FLET_WEB_PATH and uvicorn CLI you need to build it with flutter build web instead.

Hm, so something along the lines described in https://github.com/flet-dev/flet/blob/main/CONTRIBUTING.md ? Do I have to fork Flet and add my component to source code or I can use Flet extension approach with flutter build web at the end?

[InesaFitsner]

We are changing approach to creating Flet extensions in 0.26.0 which will be released within the next couple of days together with the new guide. Give it a try then and let us know if it works for you.

I've tried it but I don't see anything about web build not using static files serving whole python code on client side with pyodide. I want to use my custom Flutter components in server-client approach. Do I still need to do flutter build web in that case?

Can you make this process more simpler of creating custom flutter control or use existing packages I am trying to make it from last 3 months but again fail and again fail by error unknown control
