Connection with issue(s)

Fixes https://github.com/pichillilorenzo/flutter_inappwebview/issues/2178

Related: https://github.com/pichillilorenzo/flutter_inappwebview/pull/2189, but that PR makes changes to all sub-packages.

Instead this PR makes a hotfix-only change and version bump for flutter_inappwebview_android. Since flutter_inappwebview specifies flutter_inappwebview_android: ^1.0.12 as dependency constraint, users should be able to get this fix on the next flutter pub get when this fix is published.

Testing and Review Notes

Building the flutter_inappwebview example app as an APK in release mode, on Flutter 3.22.1 should work.

Screenshots or Videos

N/A

To Do

• [x] double check the original issue to confirm it is fully satisfied
• [x] add testing notes and screenshots in PR description to help guide reviewers
• [x] request the "UX" team perform a design review (if/when applicable)

@toshiossada Your git override isn't entirely correct. You should be depending on the correct git ref branch. I did not put my fix on master. Because the package is a federated plugin, I decided to locally test with dependency overrides for the android package (and the plugin interface, since that is a common one)

dependency_overrides:
  flutter_inappwebview_android: # https://github.com/pichillilorenzo/flutter_inappwebview/issues/2139
    git:
      url: https://github.com/navaronbracke/flutter_inappwebview.git
      path: flutter_inappwebview_android
      ref: android_release_mode_hotfix
  flutter_inappwebview_platform_interface: # https://github.com/pichillilorenzo/flutter_inappwebview/issues/2139
    git:
      url: https://github.com/navaronbracke/flutter_inappwebview.git
      path: flutter_inappwebview_platform_interface
      ref: android_release_mode_hotfix

I did locally also test against the plugin example app (but I used path overrides there, as in your PR)

[Shvet]

When will this be fixed?

[samnish07]

is the backevent issue fixed? still getting the error ERROR: R8: Missing class android.window.BackEvent (referenced from: void io.flutter.view.FlutterView.startBackGesture(android.window.BackEvent) and 1 other context)

[ghifariakbar01]

what's the correct syntax for dependency overrides using this branch?
