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'

}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
