The application which I am working on is debugging fine in emulator or in mobiles but when I try to build the apk it gives the following Error:

Building without sound null safety

I added following lines in the android directory of app level build.gradle i.e android/app/build.gradle of my project.

   lintOptions {
        disable 'InvalidPackage'
        disable "Instantiatable"
        checkReleaseBuilds false
        abortOnError false
    }

And every thing started to work fine. Check out my Gradle File

Let me help you a little bit in finding the correct place to paste the code

1: Go to your app-level build.grade. enter image description here

2:Scroll down to "android{ " paste this code carefully(not disturbing any other brakets.)

lintOptions {
            disable 'InvalidPackage'
            disable "Instantiatable"
            checkReleaseBuilds false
            abortOnError false
        }

enter image description here

3:run "flutter clean" 4:run "flutter pub get" 5:If you want to build apk of your project then run "flutter build apk"

I hope it works for you.

The solution is actual on 06.06.2022. Adding these lines in pubspec.yaml fixed the problem:

dependency_overrides:
  image_picker_android: 0.8.4+13

The issues lies in image_picker_android being updated to gradle 7.1.2. See their changelog. Following an issue on GitHub you have to update your gradle version like so:

In android/gradle/wrapper/gradle-wrapper.properties update your distributionUrl to

distributionUrl=https\://services.gradle.org/distributions/gradle-7.2-all.zip

and in android/build.gradle change the gradle version to at least 7.1.2

classpath 'com.android.tools.build:gradle:7.1.2

In my case, I had to update my Android Studio for a newer Java version too.

if you are using flutter 3.0 and image_picker, try this:

dependency_overrides:
  image_picker_android: 0.8.4+13
user_165472520

This issue is usually because the gradle plugin is outdated. If your project was created using an older version of flutter the gradle plugin will be old. The actual fix to this issue would be to upgrade the gradle plugin version.

Refer to this issue

You can use android studio to do this for you or just edit the files on your own.
