### Description

It would be great if the JS-layer (Capacitor app) could know that the underlying web view crashed and subsequently restarted. Right now there is nothing to discern these from a regular app startup and users won't be aware that data was lost.

### Platforms

### Request or proposed solution

More concretely, an issue that occur frequently is that we take a photograph via an element and do on-the-fly resize using JS and canvas, and the web view crashes, causing the page to reload. But for the user this isn't obvious, it's just a short flash when the web view reloads, and they don't know that the photograph failed and they've just lost data.

If we could listen to these events we could show a warning to the user.

This is the code on iOS today:

## Platform Support Requested

## Describe Preferred Solution

There are multiple solutions, but one could be a listener similar to , that would let us know that the app restored after a crash.

We'd then have the ability to show a warning to the user.
