android - Android Flutter 项目无法构建，出现各种错误

问题描述

我从 Github 获得源代码并下载了 zip 文件，然后用 Android Studio(Latest) 打开，然后我命令 Pub Get 下载依赖项。我想当我按下构建按钮时，它可能会像另一个颤动的安卓应用程序一样工作。

但这向我展示了很多错误，我尝试了 Stackoverflow 中的各种方法和 Google 中的解决方案，但所有解决方案都不起作用。

我使用的来源是https://github.com/nn1ks/RemoteFiles

源代码没问题，因为

我尝试了在线IDE，因为我认为问题来自IDE设置，但它也没有问题。似乎错误来自 Gradle 设置或版本。我怎么解决这个问题？

删除此警告

Your Flutter application is created using an older version of the Android embedding

您可以将其添加到活动标记下的 AndroidManifest.xml 中。

<meta-data
         android:name="flutterEmbedding"
         android:value="2" />

这应该删除警告。
