Flutter构建Release APK报错：使用compileSdk 35需AGP 8.1.0或更高

错误信息 #

[!] Using compileSdk 35 requires Android Gradle Plugin (AGP) 8.1.0 or higher.
│ │ Please upgrade to a newer AGP version. The version of AGP that your project uses is likely defined in:
│ │ /Users/tusharkhatri/Downloads/bmuptodown/android/settings.gradle,
│ │ in the 'plugins' closure.
│ │ Alternatively, if your project was created with an older version of the templates, it is likely
│ │ in the buildscript.dependencies closure of the top-level build.gradle:
│ │ /Users/tusharkhatri/Downloads/bmuptodown/android/build.gradle.
│ │
│ │ Finally, if you have a strong reason to avoid upgrading AGP, you can temporarily lower the compileSdk version in the following file:
│ │ /Users/tusharkhatri/Downloads/bmuptodown/android/app/build.gradle

解决办法 #

方法1：升级AGP到8.1.0及以上版本

• 新模板项目：打开android/settings.gradle，在plugins闭包中修改AGP版本：

  plugins {
      id "com.android.application" version "8.1.0" apply false
      id "com.android.library" version "8.1.0" apply false
      id "org.jetbrains.kotlin.android" version "1.8.10" apply false // Kotlin版本需匹配AGP，可按需调整
  }
  

• 旧模板项目：打开顶级android/build.gradle，在buildscript的dependencies中修改AGP版本：

  buildscript {
      dependencies {
          classpath "com.android.tools.build:gradle:8.1.0"
      }
  }
  

方法2：临时降低compileSdk版本（不推荐长期使用）

打开android/app/build.gradle，将compileSdkVersion改为34（或其他低于35的兼容版本）：

android {
    compileSdkVersion 34

    defaultConfig {
        // 其他原有配置保持不变
    }
}
