• I have searched for existing issues that already report this problem, without success.

Ionic Framework Version

v7.x

Current Behavior

When upgrading to latest Ionic (v7.7.3) the build fails with error:

 error TS2339: Property 'ionNavDidChange' does not exist on type 'IonNav'.

44     this.ionNav.ionNavDidChange.subscribe(async () => {
                   ~~~~~~~~~~~~~~~

Expected Behavior

This was not added to the breaking changes, and is still referenced in the documentation.
so the code should still work

Steps to Reproduce

1. create a property of type IonNav
2. try to access ionNavDidChange
3. (IDE will probably error here)
4. run build

Hello @gerhardboer thank you for this issue!

Here is a dev-build that adds the missing event properties to the Angular component wrapper for ion-nav:

npm install @ionic/angular@7.7.5-dev.11709823131.1d3df428

Let me know if you experience any issues, thanks!

[gerhardboer]

thanks for the fix, can't wait for the release so we can upgrade

[gerhardboer]

That's great to hear that the dev build worked! There's no need to close this issue since it'll be automatically closed when the pull request is merged. Thank you!
