flutter3.29 build.gradle.kts设置安卓签名

1、在android目录下创建key.properties文件

storePassword=密码
keyPassword=密码
keyAlias=别名
storeFile=jks文件完整路径

2、修改android/app/build.gradle.kts

顶部插入import java.util.Properties
import java.io.FileInputStreamval keystoreProperties = Properties()
val keystorePropertiesFile = rootProject.file("key.properties")
if (keystorePropertiesFile.exists()) {keystoreProperties.load(FileInputStream(keystorePropertiesFile))
}android块中插入
signingConfigs {create("release") {keyAlias = keystoreProperties["keyAlias"] as StringkeyPassword = keystoreProperties["keyPassword"] as StringstoreFile = keystoreProperties["storeFile"]?.let { file(it) }storePassword = keystoreProperties["storePassword"] as String}
}修改buildTypes/release中的debug为debug

build.gradle.kts完整文件

import java.util.Properties
import java.io.FileInputStreamplugins {id("com.android.application")id("kotlin-android")// The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.id("dev.flutter.flutter-gradle-plugin")
}val keystoreProperties = Properties()
val keystorePropertiesFile = rootProject.file("key.properties")
if (keystorePropertiesFile.exists()) {keystoreProperties.load(FileInputStream(keystorePropertiesFile))
