android studio - Flutter Build Error: Process 'command 'E:Flutter Appsflutterinflutter.bat'' finished with non-zero exit value 1

Question

I got this error when I try to generate a signed apk in the android studio of my flutter app - Process 'command 'E:Flutter Appsflutterinflutter.bat'' finished with non-zero exit value 1

I am able to run the app in both emulator and on my device but this error shows up only when I try to build a signed apk.

flutter doctor
[√] Flutter (Channel dev, v1.2.0, on Microsoft Windows [Version 10.0.17763.253], locale en-US)
[√] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
[√] Android Studio (version 3.3)
[√] VS Code (version 1.30.2)
[√] Connected device (1 available)

? No issues found!

Any way to fix this?

Tried flutter clean

android studio Build > clean project and rebuild project(same error)

I am doing Build > Generated signed apk > apk > release > V1(Jar signature) > Finish to build the app

Answer 1

• check if you have any assets is not founded by pubspec.yaml maybe for typo you will get Waring for that after packages get

• check AndroidX compatibilities in this Flutter app for help show this
