Google Play Storeにアプリをリリースするために、flutter build appbundleでappbundleを作ろうとしたら、下記エラーが発生した。

jksキーファイルは、Flutter公式のBuild and release an Android appに沿って、

keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload

としていた（Mac)。

公式にNoteで、

The -storetype JKS tag is only required for Java 9 or newer. As of the Java 9 release, the keystore type defaults to PKS12.

と記載があったため、末尾に-storetype JKSをつけた以下のコマンドを実行すると成功した。

keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload -storetype JKS

結果は以下の通り。

(base) username@pcname app_name %   keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload -storetype JKS

Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore /Users/username/upload-keystore.jks -destkeystore /Users/username/upload-keystore.jks -deststoretype pkcs12".
