Execution failed for task ':app:lintVitalRelease'. Flutter

Why I get these errors I try to release apk

I run "flutter build apk --release"

Execution failed for task ':app:lintVitalRelease'.

If your error says `debug/libs.jar`, build `--debug` then `--release`:

```
flutter build apk --debug
flutter build apk --release
```


If your error says `profile/libs.jar`, build `--profile` then `--release`:


```
flutter build apk --profile
flutter build apk --release
```

Upgrading gradle build tools seems to break some lints.

To fix this you can:

> If your error says debug/libs.jar, build --debug then --release. <br>
> If your error says profile/libs.jar, build --profile then --release.

If the above doesn't work you can disable the check.

Add `checkReleaseBuilds false` in `lintOptions` in the **android/app/build.gradle** file.


android {
...
lintOptions {
disable 'InvalidPackage'
checkReleaseBuilds false //<- add this line
}
}

If you're having this issue and you can't fix it with either fixes like me, you might be having different flavors. I had to run the run and run --release command for every flavor before I could build one without an error.

so
flutter run --flavor dev
... (do so for every flavor)
flutter run --flavor lastFlavor
then
flutter build apk --flavor dev (error)
... (do so for every flavor)
flutter build apk --flavor lastFlavor (SUCCESS!)

and from now on you can build every flavor without error :)

I've stuck to the latest Android Studio Gradle plugin from the `3.x` series (`3.6.4`) paired with an up-to-date Gradle version (AS plugin `3.6.4` + Gradle `6.6` yields no error for me).

_Edit: As of today July 13th 2021, Flutter 2.2.3 runs fine with Android Studio Gradle plugin version 4.2.2 and Gradle 6.8.3 (stable)_

Not sure if this is the correct way, but I solved similar issue by adding these lines

```
release {
signingConfig signingConfigs.debug
shrinkResources false // Add this line
minifyEnabled false // Also add this line
}
```

in my case, this part of the code was absent in android/app/build.gradle so i added it and it worked.



lintOptions {
disable 'InvalidPackage'
checkReleaseBuilds false
}

I have resolved this issue by adding classpath "com.android.tools.build:gradle:7.2.1" in android>build.gradle dependecies. It worked perfectly.

Note: my gradle wrapper version was https\://services.gradle.org/distributions/gradle-7.4.2-all.zip in gradle-wrapper.properties

Basically this problem occurred some of dependencies uses latest gradle version and your project version is different.

lintOptions {
disable 'InvalidPackage'
checkReleaseBuilds false //<- add this line
}


add this code will solve your problem
