Specficially https://github.com/flutter/website/blob/b9d43e2d0c5d6fb0b16e65112cd41acc4f9c58e1/src/release/breaking-changes/flutter-gradle-plugin-apply.md?plain=1#L36

The project I'm working on has no previous values for these. I've tried copying the values from another project that does work and it seems to work, although now I get Java heap space errors from Gradle .... which I know how to fix or did at one point :)

@reidbaker fyi, since this applies to Android and Gradle.

@bartekpacia fyi

My guess is heap errors are either that your Java and gradle versions are not compatible or are because you need to increase your grade heap size. I think most of our flutter projects set it to 4g.

Yes, I'm on an old project where the default was 1536mb, putting it to 4g worked.

I understand missing dependency on Kotlin (project was Java-only), but missing dependency on AGP? How did it work?

of course I'm happy to update the migration docs but I'd like to know more

Re heap errors: I'll update migration guide with this info as well, thanks

I don't know where an AGP version was defined at all in the project. What string should I be looking for?

[bartekpacia]

android/build.gradle > buildscript {} block > look for classpath 'com.android.tools.build:gradle.

For example in the following android/build.gradle:

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

// omitted more code

the AGP (Android Gradle Plugin) version is 7.3.0

In this issue I gathered how Gradle buildscripts look like in all recent Flutter versions. You probably want to migrate from the "Flutter 3.10" to "Flutter 3.16/Flutter master".

@dnfield : What change do you want made to the docs? That is unclear from this thread. Can you summarize?

How to determine the value to put in {agpVersion}. I think what @bartekpacia wrote is probably the right way.
