10.0.0/10.0.0+1 throw a compile error

[evanrich]

Updated from 9.1.0 to 10.0.0 and 10.0.0+1. Both of them give the following errors after running flutter build apk:

ERROR: Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in C:\Users\evanr\Development\ShootBase\build\app\outputs\mapping\release\missing_rules.txt.

BUILD FAILED in 2m 51s

Gradle task assembleRelease failed with exit code 1

according to chatgpt, it suggests doing either of the following:

Option 1:

Create a proguard-rules.pro

# Keep OkHttp classes for UCrop (used by image_cropper)
-keep class okhttp3.** { *; }
-dontwarn okhttp3.**
-keep class com.yalantis.ucrop.** { *; }
-dontwarn com.yalantis.ucrop.**

then edit android/app/build.gradle to add the following:

android {
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

or Option 2:

add okHttp as a dependency in my project:

dependencies {
    implementation 'com.squareup.okhttp3:okhttp:4.12.0'
    // your other dependencies
}

flutter version 3.35.3
plugin version 10.0.0 and 10.0.0+1

reverting to 9.1.0 works.

for what its worth, option 1 (using the proguard rules) fixed it.

That also worked for me, but it would be nice to have something in the docs (maybe a migration path/guide) for people who stumble across this.
