Flutter: Execution failed for task ':app:validateSigningRelease'. > Keystore file not set for signing config release
Solution 1
Well after a day of banging my head against the wall I figured this one out. I had an unknown space in my key.properties
folder at the beginning of the file name that was throwing the error. So if everything checks out, be on the lookout for random spaces!
Solution 2
- Regenerate the key
OR
Open the project "/android" in Android studio
Build -> Generate Signed Bundle / APK ..
Complete the steps...

Working on a Flutter app and I have tried all of the fixes listed on here previously and nothing has worked. I believe everything is configured correctly and in the correct places, so I need help figuring out why the signing config is still throwing this error. I have been trying for hours to find another solution with no luck. Everything is spelled correctly too. The error is below.
FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:validateSigningRelease'. > Keystore file not set for signing config release
The
key.properties
folder is in the main android folder, and theupload-keystore.jks
file is withinandroid/app
.key.properties is
storePassword=xxxx keyPassword=xxxx keyAlias=upload storeFile=/Users/..../android/app/upload-keystore.jks
And full
build.gadle
isdef localProperties = new Properties() def localPropertiesFile = rootProject.file('local.properties') if (localPropertiesFile.exists()) { localPropertiesFile.withReader('UTF-8') { reader -> localProperties.load(reader) } } def flutterRoot = localProperties.getProperty('flutter.sdk') if (flutterRoot == null) { throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.") } def flutterVersionCode = localProperties.getProperty('flutter.versionCode') if (flutterVersionCode == null) { flutterVersionCode = '1' } def flutterVersionName = localProperties.getProperty('flutter.versionName') if (flutterVersionName == null) { flutterVersionName = '1.0' } apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle" apply plugin: 'com.google.gms.google-services' // Google Services plugin def keystoreProperties = new Properties() def keystorePropertiesFile = rootProject.file('key.properties') if (keystorePropertiesFile.exists()) { keystoreProperties.load(new FileInputStream(keystorePropertiesFile)) } android { compileSdkVersion 30 sourceSets { main.java.srcDirs += 'src/main/kotlin' } lintOptions { disable 'InvalidPackage' } defaultConfig { // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html). applicationId "com.fytfeed.fytfeed" minSdkVersion 23 targetSdkVersion 30 versionCode flutterVersionCode.toInteger() versionName flutterVersionName } signingConfigs { release { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null storePassword keystoreProperties['storePassword'] } } buildTypes { release { signingConfig signingConfigs.release } } } flutter { source '../..' } dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" }
