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
 }
 }

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
 }
}

• Ahmed Raza: Signing config are already in the build.gradle, check editted code in question
• Rishabh Agrawal: can you add entire android/app/build.gradle file ? also i'm assuming you have keystore file and signing jks file
