1. 填写应用配置
基本信息
参考：https://www.jianshu.com/p/2cc3ed69f01d
appID、应用名称、应用icon、launchImage
版本信息
pubspec.yaml文件中
2. 应用程序签名
创建秘钥
AndroidTerminal中终端指令：
keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key
按提示输入信息即可
您的名字与姓氏是什么? [cy]: 您的组织单位名称是什么? [cy_studio]: 您的组织名称是什么? [cy_studio]: 您所在的城市或区域名称是什么? [HangZhou]: 您所在的省/市/自治区名称是什么? [ZheJiang]: 该单位的双字母国家/地区代码是什么? [zh]: CN=cy, OU=cy_studio, O=cy_studio, L=HangZhou, ST=ZheJiang, C=zh是否正确? [否]: 是正在为以下对象生成 2,048 位RSA密钥对和自签名证书 (SHA256withRSA) (有效期为 10,000 天): CN=cy, OU=cy_studio, O=cy_studio, L=HangZhou, ST=ZheJiang, C=zh输入 的密钥口令 (如果和密钥库口令相同, 按回车): 再次输入新口令: [正在存储/Users/liutiesong/key.jks]Warning:JKS 密钥库使用专用格式。建议使用 "keytool -importkeystore -srckeystore /Users/liutiesong/key.jks -destkeystore /Users/liutiesong/key.jks -deststoretype pkcs12" 迁移到行业标准格式 PKCS12。liutiesngdeMBP2:cayj_cystudio liutiesong$
在app内引用秘钥
android包根目录下创建文件key.properties
android/key.properties
编辑key.properties文件
storePassword=codetestkeyPassword=codetestkeyAlias=keystoreFile=/Users/liutiesong/key.jks
注意：不要将文件提交到代码库中，在.gitnore文件中忽略路径：
gradle-wrapper.jar/.gradle/captures//gradlew/gradlew.bat/local.propertiesGeneratedPluginRegistrant.java/android/key.properties
3. 在gradle中配置生效
按照路径找到文件：android/app/build.gradle
找到android {}这一行上边写入代码
defkeystoreProperties=newProperties()defkeystorePropertiesFile=rootProject.file('key.properties')if(keystorePropertiesFile.exists()){keystoreProperties.load(newFileInputStream(keystorePropertiesFile))}
在android {}这一行找到内部以下相似代码
buildTypes{release{// TODO: Add your own signing config for the release build.// Signing with the debug keys for now, so `flutter run --release` works.signingConfig signingConfigs.debug}}
将其替换为
signingConfig{release{keyAlias keystoreProperties['keyAlias']keyPassword keystoreProperties['keyPassword']storeFile keystoreProperties['storeFile']?file(keystoreProperties['storeFile']):nullstorePassword keystoreProperties['storePassword']}}buildTypes{release{// TODO: Add your own signing config for the release build.// Signing with the debug keys for now, so `flutter run --release` works.signingConfig signingConfigs.release}}
4. 打包
可以打包两种文件：APK和AAB（google最新推荐，但是部分应用商城不支持）
打包APK
flutter build apk
liutiesngdeMBP2:cayj_cystudio liutiesong$ flutter build apkYou are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size. To generate an app bundle, run: flutter build appbundle --target-platform android-arm,android-arm64,android-x64 Learn more on: https://developer.android.com/guide/app-bundle To split the APKs per ABI, run: flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi Learn more on: https://developer.android.com/studio/build/configure-apk-splits#configure-abi-splitRunning Gradle task 'assembleRelease'...
