+## 用于Google Play发布的指南
+https://www.gstatic.com/play-apps-publisher-rapid/signing-tool/prod/pepk-src.jar
+1. 下载 Play Encrypt Private Key (PEPK) 工具，请注意 [pepk-src.jar中没有主清单属性](https://stackoverflow.com/questions/44719351/googles-pepk-src-not-working)
+2. 生成密钥
+```bash
+java -jar android/google/pepk.jar --keystore=android/app/sky.jks --alias=upload --output=android/google/google_pek.zip --include-cert --rsa-aes-encryption --encryption-key-path=android/google/encryption_public_key.pem
+```
+3. 上传密钥
+上传android/google/google_pek.zip文件到谷歌Play管理中心
+4. 编译和上传 app bundle
+```bash
+flutter build appbundle --release --flavor sky -t lib/main_sky.dart
+```
+然后文件在：`build/app/outputs/bundle/skyRelease/app-sky-release.aab`
+
+- 注意，这里的sky.jks和google_pek.zip和encryption_public_key.pem都是sky渠道的，和谷歌账号对应。如果需要使用其他谷歌账号，需要更换这两个文件。
