当我想新建一个flutter项目时，flutter只是回到了欢迎界面

Question

我已经在 Android Studio 中安装了 Flutter 和 Dart 插件。 我经历了创建 Flutter 项目的所有阶段，但是当我单击“完成”时，我会看到“创建新的 Flutter 项目”对话框，但几秒钟后欢迎屏幕不断出现，我又回到了第一个阶段。 请问有人可以帮忙吗？

下面是“flutter doctor -v”命令的信息：

      You may also want to add it to your PATH environment variable.

看来你的 Flutter 安装有问题。 您可以尝试重新安装它（确保您获得了适用于您的操作系统的版本）。 第二个问题是Android SDK。 安装 Android Studio 是不够的。 尝试完成此设置说明： https : //flutter.dev/docs/get-started/install#android-setup 。
