Flutter app crashes when it use Firestore plugin in Release mode

Question

Everything works perfectly when in debug mode. It first happened when I update Flutter version to 1.10.x I could not remember which version did I use, properly. It should be 1.7.8, it was stable. To fix it I downgrade the flutter to 1.7.8+4 and also downgrade firebase related pub packages. But error still here.

Here is the solution of my nightmare.

EDIT:

Error

To fix this error, update android.enableR8=false in gradle.properties. You need to add this row cause default value true.

Finally!!! Thank you so much! I wasted a lot of time trying to fix this and would be stuck for some more time if I didn't find your solution.

I was facing the same problem, and the following changes to my build.gradle solved it.

android {
    compileSdkVersion 28

    ... 
    buildTypes {
        release {
            shrinkResources false
            minifyEnabled false
            signingConfig signingConfigs.release
            
        }
    }
}

Reference: https://github.com/FirebaseExtended/flutterfire/issues/1412#issuecomment-570161645

N.B. I know its not a perfect solution to disable minify. But it seems the firebase team is working on it and will be resolved in future update

I was able to keep android.enableR8=true by upgrading the gradle version.

android/build.gradle

from:

classpath 'com.android.tools.build:gradle:3.2.1'

to:

classpath 'com.android.tools.build:gradle:3.5.0'

android/gradle/wrapper/gradle-wrapper.properties

from:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip

to:

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

I have a similar case (same error), so I'll try to tell you what happened and maybe is the same issue that you have.

In my case I lost the keystore, so I pass through all the process of ask for a new key and so on, after that I publish a new version and my app crash in the exact way of yours, after a lot of google and stuff I figured out that have something to do with the signature (because works in debug but do not work in release), so I get into the firebase console and download again the google-services.json file, and surprise... the file have a block that wasn't there before.

After that, I test in a device with the command that you provide here (by the way thanks!), and woala! It works.

I also update the SHA-1 Signature key in the console, so that may help too. I hope that my response help you to come out to some solution.

https://github.com/flutter/flutter/issues/41576

changing to version 3.4.2 i.e com.android.tools.build:gradle:3.4.2 in build.gradle(project) , worked for me.

In case you don't want to disable R8 minification, add these rules to your proguard-rules.pro:

-keep class com.google.firestore.** { *; }
-keep class io.grpc.** { *; }
