Gradle build failed to produce an .apk file

Error Message

Gradle build failed to produce an .apk file. It's likely that this file was generated under C:\Users\...\build, but the tool couldn't find it.

Issue

I've tried moving my Flutter app to AndroidX after it kept prompting me but after doing so the above error message keeps appearing and now I can't even run my app. Any assistance on what can be done for this?

Tried

• Flutter clean
• New emulator
• Disabling AndroidX (doesn't work)

Full Issue

The plugin "cloud_firestore" is built using an older version of the Android plugin API which assumes that it's running in a full-Flutter environment. It may have undefined behaviors when Flutter is integrated into an existing app as a module.
The plugin can be updated to the v2 Android Plugin APIs by following 
https://flutter.dev/go/android-plugin-migration.
Launching lib\main.dart on Android SDK built for x86 in debug mode...

Hi @ThomasValois
the error seems caused by the cloud_firestore FlutterFire plugin,
please open the issue in the dedicated github.
Closing, as this isn't an issue with Flutter itself,
if you disagree please write in the comments and I will reopen it
thank you

Having the same issue on android , I am only using firebase_messaging plugin not cloud_firestore

Same issue here. I'm just trying to run on profile mode, but it throws this error:

Running Gradle task 'assembleProfile'... Done                     597,5s (!)
Gradle build failed to produce an .apk file. It's likely that this file was generated under ...

It also takes ages to build for some reason :/

I don't think it has anything to do with the cloud_firestore, because those are just Xlint warnings.

I never had this issue, I believe it could be related to the upgrade to Flutter v1.12, I updated recently

SOLVED

I solved my problem. This was caused because I was not entering the --flavor argument.
Maybe it can be yours too, check if you have flavors activated.

Maybe more information about this error in the future?

I had the same problem on the Mac and solution for was add to android/app/build.gradle:

android {
     ... // Your android config

    buildTypes {
        release {
            signingConfig signingConfigs.debug
        }
    }
}

This worked for me. I have been looking around for the solution to this problem for quite a while now. Thanks!

Could everyone who still has this problem please file a new issue with the exact descriptions what happens, logs and the output of 'flutter doctor -v' please.
All system setups can be slightly different so it's always better to open new issues and reference related issues.

I solved this problem.
To run flutter clean, will clean the build folder.
