i used capacitor
i wanna know, when i click back button, which url go

so i wrote this code

Plugins.App.addListener('backButton', async (data) { // data is always empty, right?
})

i think data is url data, but always empty.

You should be using your JavaScript framework's router for that. Usually, single-page apps have routers that manipulate the URL and store state using the History API. I can't give you more information without knowing more about how your app is built.
