Trying to build a cross platform connected device Google Maps enabled App using flutter framework on Android Studio Flaming 2022.2.1 Patch 2, without success. The flutter run works seemlessly until device dependency google_maps_flutter: ^2.4.0 is used under pubspec.yaml. Also after added this
flutter_plugin_android_lifecycle: ^2.0.15
the problem still here.
iOS build is ok, also Android was perfect before Google Maps was added.
Please note that I have a strage issue, with my system PATH. Doctor tell me that I have an Issue, but the PATH is perfect and built for iOS is ok. I will write another post for this strange issue.
Coming back to this question, I searched for solutions over the web, but unsuccessfully, so this is my dev environment, hoping someone can help me.
pubspec.yaml
dependencies:
http: ^0.13.6

sdk: flutter
flutter_localizations:

# Google Area

Trying to do some additional setting, for example from here maps template issue, and again nothing.
Near to become really crazy, days trying to rebuild and change setup of my dev environment, and also after post the issue on github without any answer, I have found the issue by myself.
This is definitely a bug on source code of the plugin flutter_plugin_android_lifecycle-2.0.15.
I have found the bug on its source code, in its build.gradle.
You have to go here, for MAC OS:
/Users/<your name>/.pub-cache/hosted/pub.dev/flutter_plugin_android_lifecycle-2.0.15/android
The guild.gradle, have this wrong dependence
classpath 'com.android.tools.build:gradle:4.3.1'
I have changed it in
classpath 'com.android.tools.build:gradle:7.0.2'
... and after rebuilt, the problem is SOLVED. I will try also with
classpath 'com.android.tools.build:gradle:7.2.1'
Because the previous release, in the same pub.dev directory, flutter_plugin_android_lifecycle-2.0.8, has this dependence.
Now my pubspec.yaml, for Google Maps has got only this dependencies:
google_maps_flutter: ^2.4.0
Hoping this can help you.
