Flutter itself is the issue. For some of the discussion about it: https://github.com/flutter/flutter/pull/23397
In short, following Mahi-K from the above link, you have to edit $flutterRoot/packages/flutter_tools/gradle/flutter.gradle
buildscript {
repositories {
google()
jcenter()
maven {
url 'https://dl.google.com/dl/android/maven2'
}
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
}
}
In the gradle wrapper properties gradle/wrapper/gradle-wrapper.properties you may also have to change it to 4.6 or above
