So based on documentation https://capacitorjs.com/docs/updating/3-0
Updated capacitor to latest version 3.3.3 and removed deprecated init() method from mainAcivity.kt file but getBridge() is returning null and not able to get webview.
getBridge().webView.addJavascriptInterface(JSInterface(this@MainActivity), "androidCallback")
I would appreciate any help how to get this getBridge() working so that it starts communicating with JS methods.
Apparently, this issue was solved here https://github.com/ionic-team/capacitor/pull/5328/commits and will probably be included in the next capacitor release.
