32.9 Flutter App Bundle for Android
20251006
Be sure to change com.example to com.mydomain.myapp, as appropriate, throughout the app.
We can then build the signed app bundle.
The file android/key.properties contains information required to
sign the app. The app is signed to assure that only you can sign the
app thus upload the app to the Google Play Store (if you protect your
password and key file upload-keystore.jks) .
storePassword=MYPASSWORD
keyPassword=MYPASSWORD
keyAlias=upload
storeFile=/home/kayon/upload-keystore.jksThe keystore is created with:
keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias uploadYou can check the key with:
A snippet:
Keystore type: PKCS12
...
Owner: CN=Kayon Toga, OU=Solid Pods, O=Togaware, L=Canberra, ST=ACT, C=AU
...
Certificate fingerprints:
SHA1: 2F:45:1G:67:A2:BC:D3:9E:E6:47:42:16:6F:A8:34:DD:92:62:E3:7D
...The SHA1 fingerprint here is stored with the signed app bundle as below.
Visit https://docs.flutter.dev/deployment/android for updates to
android/app/build.gradle.kts and
android/app/src/main/AndroidManifest.xml.
Now build the app bundle, signed with this key (noting that
--release is the default):
Now check the key to enusre it is your key and not the default debug key (i.e., it matches your key as above):
And note the key:
Signer #1:
Certificate #1:
Owner: CN=Kayon Toga, OU=Solid Pods, O=Togaware, L=Canberra, ST=ACT, C=AU
