Flutter工程打包——android

1 生成key（如果没有）

keytool -genkey -v -keystore D:/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

keystore  保存key的地址

alias  key的别名

跟着提示输入信息

2 配置key

新建key.properties

key.properties

storePassword= 123456 //密钥库口令
keyPassword= 123456  //密钥口令
keyAlias= key  //别名
storeFile= D:/key.jks  //key保存地址

3 配置build.dradle

def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android {...

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    } //添加

    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
        }
    }//修改

4 运行 flutter build apk

app路径build\app\outputs\apk\release\app-release.apk
