Question

我最近重置了我的电脑，所以我的项目路径发生了变化，不知道是否与此错误有关。

我尝试更改 minSdkversion，编译 SDK 版本，升级和降级所有 firebase 插件，但没有成功。

这是我的完整错误日志

这是我的 build.gradle 文件

localPropertiesFile.withReader('UTF-8') { reader ->
    localProperties.load(reader)
  }
}

if (flutterRoot == null) {
throw new FileNotFoundException("Flutter SDK not found. Define location with flutter.sdk in the 
local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'

def flutterVersionName = localProperties.getProperty('flutter.versionName')

flutterVersionName = '1.0'

从错误日志来看，这个位置的第 92 行似乎存在语法错误

C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\firebase_core-1.0.3\android\src\main\java\io\flutter\plugins\firebase\core\FlutterFirebaseCorePlugin.java

所以你可以去那个位置编辑文件并修复错误，或者我建议你删除

firebase_core: ^1.0.3

从您的 pubspec.yaml 中删除 pubspec.lock 然后运行

flutter packages get

然后重新添加

firebase_core: ^1.0.3

然后运行

flutter packages get

以便重新获取与此包相关的文件
