Standalone desktop application (with GUI) in Gleam

[sz3lbi]

Hi,
I have the case where I need to create a completely standalone desktop application with a proper GUI. I thought this might be quite a nice opportunity to get more familiar with Gleam. What may be quite important is that I am not familiar with the Erlang environment at all.
I couldn't find any GUI library (or bindings) available in Gleam. I can see that there is a module called wx in Erlang. However, in the language tour we can read about it:

External functions are useful but should be used sparingly. Prefer to write Gleam code where possible.

Therefore, I assume that creating the GUI in a different technology can be a wise decision. Let's take Flutter as the option I'm looking forward to using.
How would you approach the data exchange between these two layers, considering that both would run locally as a desktop application?
Then I can bundle both and ship them together, I guess.

Or should I stick with the wx in this case?

Importantly, I need this application to use native platform APIs, so any web-based solutions (similar to Electron) are out of the question.

wx and scenic are the most popular desktop GUI libraries for Erlang. You could also try ones made for JavaScript
