Start with the crash frames in Flutter's ios_gl_render_target.mm and ios_surface_gl.mm, then trace the SetOwnerViewController path through platform_view_ios.mm and FlutterEngine.mm. Reproduce the iOS crash using the reported Flutter 1.12.13+hotfix.9 and Xcode 12.2 setup. Done means the reported OpenGLES crash no longer occurs when the Flutter view container is initialized.
