cordova information: (run $> cordova plugin list)

If you use @ionic-native/google-maps, please tell the package.json (only @ionic-native/core and @ionic-native/google-maps are fine mostly)

"@ionic-native/core": "^5.27.0",
"@ionic-native/google-maps": "^5.5.0",

Current behavior:
If you hide the map with the map.setDiv() method through the Ionic lifecycle methods ionViewWillLeave it works the first time. But the second time it can't hide the map.

To reproduce in the repository you need to go to "Next page" and back two times. The second time the error occurs. In the browser platform the error occurs on the first call.

Expected behavior:
Should hide the map without errors.

Ok, I fixed problem, however you also need to change your code.

First, please upgrade @ionic-native/google-maps

$ npm uninstall @ionic-native/google-maps
$ npm install @ionic-native/google-maps@5.27.0-beta-20200630

---

Second, you also need to reinstall the cordova-plugin-googlemaps

$ ionic cordova plugin rm cordova-plugin-googlemaps
$ ionic cordova plugin add https://github.com/mapsplugin/cordova-plugin-googlemaps#multiple_maps
$ ionic cordova plugin list

cordova-plugin-googlemaps 2.8.0-20200709-1800 "cordova-plugin-googlemaps"  <-- make sure `2.8.0-20200709-1800`

---

Third, modify your code
https://github.com/wf9a5m75/ionic-native-maps-error-fixed/

---

Then the app should work like this
