The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.

my apologies that bug report is kind of messy. basically when I add this flutter-permission-handlers library I get multi dex issues. I am new to flutter so I am using default (flutter generated) settings for gradle files. I tried 'flutter clean'. I tried "multiDexEnabled true" in build.gradle. I continue to troubleshoot. Some tips say it might be related to AndroidX, but again I'm using all default flutter build configs so I don't know why that would be the cause.

after adding defaultConfig { multiDexEnabled true } to build.properties I was receiving a different error:
':app:transformClassesWithMultidexlistForDebug',
so I researched that. there are several multi dex issues open/closed:
flutter/flutter#23929
flutter/flutter#23131

FIXED
I added to location_permissions build.gradle

android {
    defaultConfig {
        multiDexEnabled true
}

I added to gradle.properties

android.useAndroidX=true
android.enableJetifier=true
