Answer 2

Author of google_maps_webservice plugin (https://pub.dev/packages/google_maps_webservice) does not release flutter 2.0.2 compatible version yet. You can switch to 0.0.20-nullsafety.2 version (https://pub.dev/packages/google_maps_webservice/versions/0.0.20-nullsafety.2)

add explicitly

google_maps_webservice: ^0.0.20-nullsafety.2

to dependencies in pubspec.yaml

Update the compileSdkVersion to 30 in my app/build.gradle

do not forget run:

flutter clean
flutter pub get
