Signing Configs

signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
            storePassword keystoreProperties['storePassword']
        }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }

Solution

Your error SigningConfig "release" is missing required property "storeFile" clearly says that you are missing signing details.

You need to add signing details like keyAlias, keyPassword ... under your android/app/build.gradle file

In short you need to let Android know about your signing details so that they can sign your app and provide you a release. you can create your debug build with signing detail

here are the sample format

signingConfigs {

    release {
        keyAlias keystoreProperties['keyAlias']
        keyPassword keystoreProperties['keyPassword']
        storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
        storePassword keystoreProperties['storePassword']
    }
}

buildTypes {
    release {
        signingConfig signingConfigs.release
    }
}
