I'm curious, why does the backend depend on Slint?

I thought at first that the backend would be using public API only and so that would simplify things with regards to publishing it with a different version and a name like slint-android 0.3.0 or something. But I guess this is futile.
Do you want me to go ahead and use the internal instead?

I think that makes sense yeah. Either that or remove the FIXME :)

This was just as the example. Do you think it's bad to have?

For an example, I think it's weird yes :)

Perhaps it would make sense to make this not a "listener" but an event filter. So a function that we say will be called before we process the event, and the provider can choose to "consume" the event (i.e. prevent it from reaching Slint).

I wanted to call filter, but filter doesn't really make more sense.
The event that are there cannot really be filtering without introducing bugs.
What would be an example of an use case of filtering?
This also doesn't include the input event that are handled by Slint only.

The main example I can think of are new events that we don't handle. Such as the save/restore for example.
This is a backend that implement a slint::platform for android-activity
This also adapt the
todoexample so it can be run on android.In order to run it on android, the
#wasm#lines in the todo/Cargo.toml need to be removed, and thetodo example can be run with cargo-apk:
cargo apk run -p todo --target aarch64-linux-android --lib(and the proper env variable needs to be defined for the NDK and the SDK)This work is sponsored by NLnet
