Flutter Picking Wrong Keystore path and giving error key.jks not found - dart

Question

I followed all the steps on the Flutter official site and thought I'd done everything correctly but it is failing to locate the keystore file when I build it.
This is the error message I get showing it taking wrong path instead of
D:\flutterapps\testapp\key.jks:
PS D:\flutterapps\testapp> flutter build apk
Initializing gradle... 1.3s
Resolving dependencies... 4.3s
Gradle task 'assembleRelease'...
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:validateSigningRelease'.
> Keystore file 'D:\flutterapps\testapp\android\app\ D: lutterappspublishkey.jks' not found for signing config 'release'.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Answer 1

On Windows you have to use 2 backslashes to indicate the path separation.
In your key.properties, you should have something like this:
storeFile=D:\\flutterapps\\testapp\\key.jks
You don't need to copy your key.jks file to your flutter project.

Answer 2

modified key.properties file with
storePassword=123456
keyPassword=123456
keyAlias=key
storeFile=key.jks
instead of this
storePassword=123456
keyPassword=123456
keyAlias=key
storeFile=D:\flutterapps\testapp\key.jks
and also moved key.jks to
D:\flutterapps\testapp\android\app\key.jks
as this path shown in error inside terminal
Thanks all.

Answer 3

it's wherever call it from in your build.gradle. insert this:
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
and call this in above your android{}:
def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
and that key.properties file (which should be in your root android folder) should have this:
storePassword=12345
keyPassword=12345
keyAlias=key
storeFile=/Users/me/somekey.jks

Answer 4

Yeah, for me... I forgot to change my signingConfig to singingConfigs.release in my build.gradle file.
buildTypes {
release {
//CHANGE THIS TO RELEASE
signingConfig signingConfigs.debug
}
}

Answer 5

In build.gradle
Replace
def keystorePropertiesFile = rootProject.file('key.properties')
to
def keystorePropertiesFile = rootProject.file('app/key.properties')

Answer 6

I was having the same issue, I ended up having quotes around my path.
In key.properties, change
storeFile="D:\\mypath\\tokeystore\\key.jks"
to
storeFile=D:\\mypath\\tokeystore\\key.jks
