terminal执行下列命令:
1.生成key(如果有现成的Key跳过这一步)
输入命令：keytool -genkey -v -keystore D:\git_boyacx\AndroidGit\flutter_study-master/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key 如下图
2.key.properties创建
在android目录下创建此文件后设置密码，
storePassword=<password from previous step> //输入上一步创建KEY时输入的 **库 密码 keyPassword=<password from previous step> //输入上一步创建KEY时输入的 ** 密码 keyAlias=key storeFile=<E:/key.jks> //key.jks的存放路径
如图：
3.配置key注册
进入项目目录的/android/app/build.gradle文件，在android {这一行前面，加入如下代码：
//apk打包配置
def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
把如下代码：
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.debug
}
}
替换为：
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.
signingConfig signingConfigs.release
}
}
如下图：
4.执行flutter build apk
