title: Flutter build appbundle failed
body: <p>I'm trying to build my flutter appbundle but I got an error saying:</p>
  <pre><code>Execution failed for task ':app:validateSigningRelease'.
  &gt; Keystore file '/Users/user/key.jks' not found for signing config 'release'.
  
  </code></pre>
  <p>Here is my release in build.gradle:</p>
  <pre><code>
  signingConfigs {
          release {
              keyAlias keystoreProperties['keyAlias']
              keyPassword keystoreProperties['keyPassword']
              storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
              storePassword keystoreProperties['storePassword']
          }
      }
      buildTypes {
          release {
              signingConfig signingConfigs.release
          }
      }
  </code></pre>
  <p>Is there a way to fix this?</p>
