Flutter in Android Studio: Build Bundle/APK greyed out

Question

I installed Flutter and Android Studio following this link here: https://flutter.dev/docs/get-started/editor

I've been coding in flutter for two months now and can run my app in simulator or on a connected device no problem.

But when I try to actually build an apk via "Build" --> "Build Bundle(s) / APK", this option is greyed out.

Android Studio: 3.3.2

Answer 1

You can't build apk using Build option in Android Studio if you are running your Flutter project.

There are 2 solutions to build it.

1. In terminal, write flutter build apk (this will build apk for release version not the debug version)

2. Open your module in Android Studio and you can use Build option of the Android studio to build the debug apk.

For option 2, you can go to build.gradle file and you should see an option in Android Studio asking you to open the module separately (see the screenshot) Tap on this option and you can then build your apk in both debug and release mode.

Answer 2

I realize this might have already been answered, but I have another solution to this issue. I was having the same problem after modifying my pubspec.yaml file, so after trying to build within terminal nothing would happen. Apparently, you have to open the .yaml file within Android Studio from your project directory in order to for AS to realize that there's been a change to the file. After I opened the file from the project folder, the option for Build > flutter > Build Bundle(s) /APK > Build App Bundle finally reappeared again. Just sharing my experience and hope it can help someone else who may come across this rather strange issue.
