How to build signed apk from Android Studio for Flutter

Issue

Is there a way to build an apk for flutter in Android Studio?

I have seen this guideline: https://flutter.dev/docs/deployment/android
But here flutter console is used to build apk.

Solution

You can build the Apk/AppBundle using IDE and command line.

  • Building APK/AppBundle through IDE:

    Step-1

    In Android Studio’s tab bar, click on Tools and then Flutter and then Open Android module in Android Studio:

    Step-3

    Having opened the project, click on Build and then Generate Signed Bundle / APK ...

  • Building APK/AppBundle through command:

    Step-1:

    Modify your build.gradle(app) file and include your key information there:

    android {
        compileSdkVersion 31
        signingConfigs {
            release {
                storeFile file("<path-to-keys.jks>")
                storePassword "********"
                keyAlias "<key-alias>"
                keyPassword "********"
            }
        }
        buildTypes {
            release {
                signingConfig signingConfigs.release
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
    }
    

    Step-2:

    Build AppBundle:

    flutter build appbundle --target-platform android-arm,android-arm64,android-x64 --obfuscate --split-debug-info=/<directory>
    

    Build APK:

    flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi --obfuscate --split-debug-info=/<directory>
