[Android] java.lang.NullPointerException: Parameter specified as non-null is null: method zyz.flutter.plugin.flutter_google_street_view.FlutterGoogleStreetView.onStreetViewPanoramaChange, parameter location

The app crashes when setting a location where Street View does not exist.

same here..

[foxide123]

Same. Tried to run the example application but get this error. Overriding onStreetViewPanoramaChange and catching the exception doesn't help.

[liorboyango]

That's an sdk issue, see here: https://issuetracker.google.com/issues/222232904

And BTW, if you set initPanoId instead of initPos it won't crash - not very useful but perhaps it might help someone

[liorboyango]

I made a fork with a fix, hope it helps:

  flutter_google_street_view:
    git:
      url: https://github.com/liorboyango/flutter_street_view.git
      path: flutter_google_street_view
      ref: master

I am also having this issue. Adding the above to my pubspec.yaml gives the following issue. Any help would be appreciated:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':flutter_google_street_view:compileDebugJavaWithJavac'.
> error: invalid source release: 17

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

Same issue here when build with Codemagic

@liorboyango would it be possible to merge your fork and publish a new release to pub.dev?

Set your Android env to use Java17

@liorboyango Still app is crashing, please tell the solution for this, i used initPanoId instead of pass lat longs, and app crashes.

@liorboyango @lazytesting @Nicoeevee @yishaiSilver @BalaSundar009 @hukusuke1007

Does somebody find the solution for this? Apps keep crashing with the package flutter_google_street_view: ^3.1.4, giving error in console com.google.maps.api.android.lib6.common.apiexception.f: java.lang.NullPointerException: Parameter specified as non-null is null: method zyz.flutter.plugin.flutter_google_street_view.FlutterGoogleStreetView.onStreetViewPanoramaChange, parameter location

What is the solution for this? because there is not any update on package since 14 months, what to do next? Please reply
