Flutter构建失败：无法找到com.android.application 7.3.0插件

问题分析 #

错误提示无法找到com.android.application:7.3.0插件，核心原因是插件版本与Flutter版本不兼容或官方仓库无法正常访问。

解决方案 #

1. 匹配Flutter与Android Gradle插件(AGP)版本 #

不同Flutter版本要求对应AGP版本，先执行flutter doctor查看当前Flutter版本，再调整版本匹配：

2. 修改settings.gradle配置 #

根据匹配的版本，更新settings.gradle中的插件版本：

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    // 替换为兼容的AGP版本，示例为Flutter3.10+对应的7.4.2
    id "com.android.application" version "7.4.2" apply false
    // 对应兼容的Kotlin版本
    id "org.jetbrains.kotlin.android" version "1.8.20" apply false
 }

如果是网络无法访问官方仓库，在pluginManagement的repositories中添加国内镜像：

pluginManagement {
def flutterSdkPath = {
    def properties = new Properties()
    file("local.properties").withInputStream { properties.load(it) }
    def flutterSdkPath = properties.getProperty("flutter.sdk")
    assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
    return flutterSdkPath
}
settings.ext.flutterSdkPath = flutterSdkPath()
includeBuild("${settings.ext.flutterSdkPath}/packages/flutter_tools/gradle")

repositories {
    // 添加阿里云镜像
    maven { url 'https://maven.aliyun.com/repository/google' }
    maven { url 'https://maven.aliyun.com/repository/central' }
    maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
    google()
    mavenCentral()
    gradlePluginPortal()
  }
}  

3. 清理缓存并重新构建 #

执行以下命令彻底清理缓存后重新构建：

flutter clean
cd android
./gradlew clean
./gradlew build --refresh-dependencies
cd ..
flutter run
