[google_maps_flutter] App is lagging when initializing Google Maps #28493
Description
I am just building the Google-Maps widget in my Stateful Widget. This will be opened with the Navigator via a Button click. But as soon, as I click, the app is lagging, while initializing the map.
When removing the widget, everything is fine.
I tried to set a CircularProgressIndicator and then, setting the map-widget async, but running into the same problem, as soon, as it gets build.
I also downloaded and ran the example app from the google-maps-package with the same lagging.
How should the map be initilized, that it is first loaded and then set without lagging?
