1.生成key
2.創(chuàng)建key.properties
3.配置app的build.gradle

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

signingConfigs {
    release {
        keyAlias keystoreProperties['keyAlias']
        keyPassword keystoreProperties['keyPassword']
        storeFile file(keystoreProperties['storeFile'])
        storePassword keystoreProperties['storePassword']
    }
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }

4. 命令行執(zhí)行

flutter build apk 

5. 生成的app-release.apk 就在項目的output/apk/release目錄下

6. 安裝 生成的apk包到手機

adb install app-release.apk
