Flutter:gradle build failed with error “A problem occurred evaluating root project 'android' > A problem occurred configuring project ':app'.”

问题

My flutter app runs fine on the emulator, runs fine on my android when connected via USB, but crashes before opening when updated from the play store. Does the same to everyone else that has tried the update. So I thought I would try rebuilding as apk and install from firebase distribution.

flutter build works fine if i run as appbundle, or apk but only fails on apk --split-per-abi. I am not sure if this error has to do with why it's crashing or if it's a new problem.

Here is the error I get when running flutter build -v apk --split-per-abi

I seem to keep running into other issues related to this being caused by the gradle version or maybe google services version. I've tried several different versions. Currently using https://services.gradle.org/distributions/gradle-6.5-all.zip and

classpath 'com.android.tools.build:gradle:4.1.0'
classpath 'com.google.gms:google-services:4.1.0'

I also checked the file in the error message, line 646 contains: abiVersionCode * 1000 + variant.versionCode

I've run flutter clean and here is my flutter doctor -v output:

Change the version of gradle on android/build.gradle file to 3.5.0.

buildscript {
repositories {
    google()
    jcenter()
}

dependencies {
    ...
    classpath 'com.android.tools.build:gradle:3.5.0' // Use this version
}
}

On android/gradle/wrapper/gradle-wrapper.properties, your distributionUrl should also have the following gradle version.

gradle-5.6.2-all.zip

so that you won't run into any other issues.

Finally, run these commands

rm -rf android/.gradle
rm -rf $HOME/.gradle # This is for Mac users
flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi

It should work like a charm! And update Gradle later on when things get little matured and stable.
