android - 任务 ':google_api_headers:compileDebugKotlin' 执行失败

Question

更新到 Dart 3.0 后，当我在 Android 模拟器上启动应用程序时出现此错误。
对于 iOS 物理设备，它的构建还可以。不幸的是，无法尝试使用 Android 物理设备。有任何想法吗？

作为临时解决方案

从 Flutter 3.0 降级

    flutter downgrade 2.10.5

打开产生错误 GoogleApiHeadersPlugin.kt 的文件(cmd + 在 macOS 的控制台中单击它)
并剪掉所有的 try catch 部分

    try {
                val info: PackageInfo
                if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.P) {
                    info = context!!.packageManager.getPackageInfo(call.arguments<String>(), PackageManager.GET_SIGNING_CERTIFICATES)
                    for (signature in info.signingInfo.apkContentsSigners) {
                        parseSignature(signature, result)
                    }
                } else {
                    @Suppress("DEPRECATION")
                    info = context!!.packageManager.getPackageInfo(call.arguments<String>(), PackageManager.GET_SIGNATURES)
                    @Suppress("DEPRECATION")
                    for (signature in info.signatures) {
                        parseSignature(signature, result)
                    }
                }

            } catch (e: Exception) {
                result.error("ERROR", e.toString(), null)
            }

所以如果方法是空的并且什么都不做

if (call.method == "getSigningCertSha1") {}

我没有足够的知识来说明这样做的后果是什么，但我的应用程序正在运行，并且所有谷歌 API 也在运行(谷歌地图、谷歌登录、Firebase)
我建议您将已删除的代码保存在某处。
