google_maps_flutter and flutter_unity_widget crash Surface Texture

[shifugate]

Hello everyone, sorry about my english.

I am using google_maps_flutter: ^2.1.1 and flutter_unity_widget: ^4.2.5+1 in same project.

The problem:

After going to arcore in unity and return to google maps in flutter, the app freezes because the surfacetexture isn´t release by unity widget.

Any workround for this?

Thanks.

Hmmm, this is interesting, taking a look at it.

Hello again.

I resolved the problem.

I add in app initialization:
AndroidGoogleMapsFlutter.useAndroidViewSurface = true;

This append the maps in others native android.view.View to the view hierarchy.

Thanks.
