android/app/build.gradle 配置如下

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
}


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

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

android {
    namespace "com.heradal.LS"
    compileSdkVersion 34
    ndkVersion flutter.ndkVersion

    // Packaging error resolution
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
        disable 'InvalidPackage'
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.heradal.LS"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
        // minSdkVersion flutter.minSdkVersion
        targetSdkVersion flutter.targetSdkVersion
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        minSdkVersion 21
    }

    applicationVariants.all { variant ->
        variant.outputs.all {
            def appName = "LH" // 文件名
            def version = variant.versionName // 版本号
            def buildType = variant.name // 包类型，debug 还是 release
            def createTime = new Date().format('MMddHHmm') // 打包时间 2021_09_25_16_45_52
            if (buildType == "debug") {
                outputFileName = "${appName}_${version}_${buildType}_${createTime}.apk"
            }
            if (buildType == "release") {
                outputFileName = "${appName}_${version}_${buildType}_${createTime}.apk"
            }
        }
    }
     //签名信息
    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword 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.
            debuggable false
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
            ndk{ // 必须加入这部分，否则可能导致编译成功的release包在真机中会闪退
                abiFilters "armeabi-v7a"
            }
        }
        debug {
            ndk {
                //这里要加上，否则debug包会出问题,后面三个为可选，x86建议加上不然部分模拟器回报错
                abiFilters "armeabi", "armeabi-v7a", "arm64-v8a",  "x86"
            }
        }

    }
}

flutter {
    source '../..'
}

dependencies {}

android/app/proguard-rules.pro 新增proguard-rules.pro文件

#Flutter Wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }

说明

proguard-rules.pro 里面需要配置的是你使用的安卓包

-keep class com.alipay.deviceid.** { *; }
-keep class net.security.device.api.** {*;}
-keep class org.json.** { *;}
-keep class com.alibaba.fastjson.** {*;}
-keep class com.alibaba.sdk.android.oss.** { *; }
-keep class chat.konnect.**{*;}
-keep class konnect_im_sdk.**{*;}

-dontwarn okio.**
-dontwarn org.apache.commons.codec.binary.**

-keepclassmembers,allowobfuscation class * {
@com.alibaba.fastjson.annotation.JSONField <fields>;
}

如我本地使用konnect_im_sdk 就需要配置进去

android/app/build.gradle 中

minifyEnabled 使用压缩

shrinkResources 去除没有使用的资源类似前端摇树优化

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 开启混淆文章来源地址https://www.toymoban.com/news/detail-781625.html
