补充说明 #

仅需启动应用生成debug.keystore文件，已尝试多种同类问题解决方案但无效，请求帮助。

解决方案 #

1. 强制统一依赖版本 #

错误显示location模块引用了版本号错误的com.google.android.gms:play-services-location:16..（多了一个点），需要强制所有子模块使用你在app中指定的21.0.1版本。

修改android/build.gradle中的subprojects部分，添加版本强制策略：

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.configurations.all {
        resolutionStrategy {
            force 'com.google.android.gms:play-services-location:21.0.1'
        }
    }
}
subprojects {
    project.evaluationDependsOn(':app')
}

2. 清理缓存并重新构建 #

执行以下命令清理缓存：

flutter clean

然后删除android/.gradle文件夹，最后重新运行：

flutter run

3. 检查并更新location插件版本 #

打开pubspec.yaml，查看你使用的location插件版本，确保是最新稳定版。如果版本较旧，更新后执行flutter pub get再重新构建。
