There are three things I can suggest to help. The first is to do a full rebuild by first running flutter clean and then running again. Occasionally things get a little bit messed up between flutter & android, and that helps.

The next thing I would do is check that you're getting the same version of all the Play services. For some reason gradlew sometimes messes that up. Run gradlew app:dependencies from the android (or ./gradlew if you're on mac/linux). If you're getting different versions, add them all as dependencies of the same version.

For example, in my android/app/build.gradle, I had to set

implementation 'com.google.android.gms:play-services-base:15.0.2'
implementation 'com.google.android.gms:play-services-vision:15.0.2'

even though Gradle should have sorted that out. In particular look out for com.google.android.gms:play-services-location as it's a dependency of the geolocation package. Same goes for the com.android.support libraries.

If that still doesn't work, try running the gradle build directly, and in particular looking at the stack trace (gradlew app:build --stacktrace from the android folder) to see if it tells you anything. You could then post that, or take a look at the generic Android questions for a solution. It could be that you need to enabler multi-dex, although I don't think so.

Thanks for this info. But, not super acquainted with all these level of android configuration stuff. I tried flutter clean. But, that didn't work. Tried to run those gradlew app:dependencies & ./gradlew commands but those also didn't work. Maybe I need to install Gradle on my system. But Gradle website seems down from yesterday. I've posted my app>build.gradle file in my post. Is there anything wrong in that, which may be causing this issue.

I believe this is an issue with geolocation gradle version of firebase and your flutter version being incompatible. Try adding multiDexEnabled true to your build gradle. If that does not solve it open your flutters android project in android studio and go to the geolocation build gradle and change dependencies version to classpath 'com.android.tools.build:gradle:3.1.2' & at the bottom update the play services to api "com.google.android.gms:play-services-location:15.+".

Finally, I've fixed this by following the steps as mentioned by @rmtmckenzie.

In my android/app/build.gradle I added following piece of code &

configurations.all {
    resolutionStrategy {
        force 'com.google.android.gms:play-services-location:15.0.1'
    }
}

and enabled multiDexEnabled true

defaultConfig {
    multiDexEnabled true
}

With this setting now, my whole app working fine.

In your app's top level build.gradle update classpath. For me classpath 'com.android.tools.build:gradle:3.5.3' is working fine.
