[webview_flutter] Send history events

[wwwdata]

Description

Send URL change events when the user navigates in the Browser. This also works for JavaScript Navigation that does not actually make any request and therefore would not trigger page load or finish events.

hi @wwwdata could you please rebase (& start the next version number)

Just rebased, increased version number and pushed. Thanks for the fast feedback

[wwwdata]

@ened Thanks a lot for the good review feedback. Implemented the requested changes.

[MattisBrizard]

Hi @wwwdata, is this pull request still active ? I also need this implementation, and see that's it is an old PR. I see that it requires @amirh approval, any update on this feature ? Thanks.

[wwwdata]

So far I didn't hear anything official... I would be happy to rebase and fix all conflicts here again if somebody then also does a review...

[wwwdata]

Ok, it's rebased again. We're only in 10 months waiting for a review, so let's give it some time :)

[jcgoodru]

This would be a great feature to have :)

[Hixie]

@wwwdata Any chance you have the time to look at this again? It looks like it's so close to landing.

[christopherfujino]

I am going to close this as stale. Feel free to re-open if you are going to rebase and apply requested changes.

I am planning to look at adapting this to the current state of the plugins once the iOS conversion to Dart+Pigeon is complete.

[stuartmorgan]

The Dart conversion is complete, but in the meantime we found https://github.com/flutter/flutter/issues/94051 which blocks this, since we currently implement WebViewPlatformCallbacksHandler in our implementations, making changes to it breaking changes. We're actively working on that issue, and hope to have it resolved soon.

[stuartmorgan]

Status update from triage: this is still blocked, but we hope to have it unblocked soon.

[stuartmorgan]

This is unblocked now that v4 has landed. @bparrishMines This is one we should look at updating.

[stuartmorgan]

Closing as this was obsoleted by https://github.com/flutter/plugins/pull/7113; the implementation had changed enough that it was easiest to start a new PR rather than update this one. Thanks!
