Can you show the build.gradle file ?

Hi @MockAirplane700
Have followed these steps?

Create a keystore
Reference the keystore from the app
Configure signing in gradle

Could you please provide the contents of your /android/app/build.gradle
and /android/key.properties (make sure no sensitive information is included).
Thank you

My build.gradle:
def 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  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'
}
def keystoreProperties =  new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
keystoreProperties.load( new FileInputStream(keystorePropertiesFile))
}
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'
android {
compileSdkVersion 28
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 "package name"
    minSdkVersion 21
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}

signingConfigs {
    release {
        keyAlias keystoreProperties['key alias']
        keyPassword keystoreProperties['keyPassword']
        storeFile keystoreProperties['app/storefile.jks] ? file(keystoreProperties['app/storefile.jks']) : null
        storePassword keystoreProperties['StorePassword']
    }
}

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.release
    }
}

}
flutter {
source '../..'
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

My key.properties:
storePassword
keyPassword
keyalias
storeFile

storeFile should contain the path of jks file.
Keep your jks file away from git commit
The line inside signing configs of build gradle is wrong -
storeFile keystoreProperties['app/storefile.jks] ? file(keystoreProperties['app/storefile.jks']) : null
change the above to
storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
Make sure key.properties has correct values regarding each key
storePassword=password
keyPassword=password
keyAlias=alias
storeFile=path to jks file

In case you are keeping it in your app folder the path would be
storeFile=app/storefile.jks
Doing this should do the task for you

I will try that immediately thank you

I have tried what you suggested. The store file folder path is set.
storeFile keystoreProperties['the name. of the store file'] ? file(keystoreProperties['the name of the store file']) : null
I have the same error again. Please see verbose attached

storeFile keystoreProperties['the name. of the store file'] ? file(keystoreProperties['the name of the store file']) : null
this is not what i said.
Please see my below comment .

storeFile should contain the path of jks file.
Keep your jks file away from git commit
The line inside signing configs of build gradle is wrong -
storeFile keystoreProperties['app/storefile.jks] ? file(keystoreProperties['app/storefile.jks']) : null
change the above to
storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
Make sure key.properties has correct values regarding each key
storePassword=password
keyPassword=password
keyAlias=alias
storeFile=path to jks file

yeah that is what I did. In my key.properties file there is a correct store password, keypasswod, key alias and store file, the file is on my desktop so looks like /Users/sdsd/key.jks.
As for the line inside of build Gradle, do you mean that I must not change the words store file to the directory that the store file key.jks located?

yeah basically consider keyProperties something similar to a json. So In build.gradle when you use keyProperties['storeFile']
It will return the path of the file.
What you have done currently is passing keystore file name in keyProperties['the name of the store file'] which will return null
because there is no key in keyProperties.

I see now. I have taken your advice and change the name accordingly. But now I am getting a new error
A problem occurred evaluating project ':app'.

Could not get unknown property 'keycstoreProperties'

I do not know what is causing it. I thought maybe its because of the misspelling, "keycstoreProperties" but I cannot find it in my code. The only place in my code with the explicitly mentions it is where I declared it as part of new Properties, but its spelt correctly there

Because there is a typo in "keycstoreProperties"  an extra c after key

I found and fixed the typo but now it cannot find the key.jks file even though it is there. This is the error:

Keystore file '/Users/siziba/AndroidStudioProjects/synthex_klutch_release/android/app/</Users/siziba/Desktop/key.jks>' not found for signing config 'release'.

I found and fixed the typo but now it cannot find the key.jks file even though it is there. This is the error:

Keystore file '/Users/siziba/AndroidStudioProjects/synthex_klutch_release/android/app/</Users/siziba/Desktop/key.jks>' not found for signing config 'release'.

I  think this is a path issue I will show you one example from my project -
storeFile=/Users/princesrivastava/keys/evoqystest.keystore
I am using Mac

That was helpful. it turns out I had angle brackets around the path. I finally got it build! Thank you

it is important to make sure that the values are written without "" this cause a lot of problems
in android > key.properties
storePassword=457457
keyPassword=788485
keyAlias=upload
storeFile= C:/Users//upload-keystore.jks

I'm trying to use a created key, is has been used in other non flutter apps, only at this app i getting problems...
My android > key.properties
storePassword=xxxx
keyPassword=xxxxx
keyAlias=OMAndroidKeyStore
storeFile= C:/Users/OM/Documents/

Get the error:

What went wrong:
Execution failed for task ':app:validateSigningRelease'.

Keystore file 'C:\Users\OM\Documents\OMAndroidKeyStore' not found for signing config 'release'.

I changed it..
android > key.properties
storePassword=xxxx
keyPassword=xxxxx
keyAlias=OMAndroidKeyStore
storeFile= C:/Users/OM/Documents/

Getting the error:

What went wrong:
Execution failed for task ':app:packageRelease'.

A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable

OMAndroidKeyStore' found in keystore C:\Users\OM\Documents\OMAndroidKeyStore\OMAndroidKeyStore.jks

Anyone can help me?

A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable
com.android.ide.common.signing.KeytoolException: Failed to read key OMAndroidKeyStore from store "C:\Users\OM\Documents\OMAndroidKeyStore\OMAndroidKeyStore.jks": No key with alias '
OMAndroidKeyStore' found in keystore C:\Users\OM\Documents\OMAndroidKeyStore\OMAndroidKeyStore.jks

Anyone can help me?

Please make sure that the alias you used during creation of the key with keytool is exactly the same as passed in key.properties as keyAlias, e.g. as in https://flutter.dev/docs/deployment/android :
keytool -genkey -v -keystore c:\Users\USER_NAME\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
the sting following -alias parameter is the descriptor you need to match (in above example it's upload), in your case it should have been OMAndroidKeyStore.
I believe you may want to create a new key store file from scratch, paying attention to the -alias parameter.
