3、构建签名

使用keytool，可以直接在Android Studio 的terminal里面操作

口令：keytool -genkey -v -keystore G:/keys/test.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias key

区分开来的字段需要注意，存储路径和别名，路径里面的文件自己创建。

输入口令之后，开始填写一些信息，名字，公司….到了【否】这里写y，继续，没有报错的话签名就构建ok了，notepad++打开一坨乱码，我还在怀疑能用不呢。

4、创建 key.properties

路径：<app dir>/android/key.properties 文件手动创建

主要用来引入刚刚的签名文件

key.properties

<pre style=”margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: “Courier New” !important; font-size: 12px !important;”>storePassword = exanple 这是你创建签名写的密码
keyPassword = exanple 这是你创建签名写的密码
keyAlias = key 口令里面的alias key 对应
storeFile = G:/andro/example/android/app/keys/test1.keystore 绝对路径</pre>

**5、配置混淆 **

路径：<app dir> /android/app/proguard-rules.pro 手动创建

proguard-rules.pro

[

复制代码

](javascript:void(0); “复制代码”)

复制代码

<pre style=”margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: “Courier New” !important; font-size: 12px !important;”>#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.* { *; }</pre>

](javascript:void(0); “复制代码”)

6、修改builg配置build.gradle

路径：<app dir>/android/app/build.gradle

build.gradle

[

复制代码

](javascript:void(0); “复制代码”)

复制代码

<pre style=”margin: 0px; padding: 0px; overflow: auto; overflow-wrap: break-word; font-family: “Courier New” !important; font-size: 12px !important;”>def keystorePropertiesFile = rootProject.file(“key.properties”) // 引入
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
android {
compileSdkVersion 28

lintOptions {
    disable 'InvalidPackage'
}

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "myapp.flutter_kiminitodoke"
    minSdkVersion 16
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
signingConfigs {
    release {
        keyAlias keystoreProperties['keyAlias']
        keyPassword keystoreProperties['keyPassword']
        storeFile file(keystoreProperties['storeFile'])
        storePassword keystoreProperties['storePassword']
    }
}

buildTypes {
    release {
       signingConfig signingConfigs.release  // debug
        minifyEnabled true
        useProguard true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}</pre>
