當我想新建一個flutter項目時，flutter只是回到了歡迎界面

Question

我已經在 Android Studio 中安裝了 Flutter 和 Dart 插件。 我經歷了創建 Flutter 項目的所有階段，但是當我單擊“完成”時，我會看到“創建新的 Flutter 項目”對話框，但幾秒鍾后歡迎屏幕不斷出現，我又回到了第一個階段。 請問有人可以幫忙嗎？

下面是“flutter doctor -v”命令的信息：

      If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location.
      You may also want to add it to your PATH environment variable.

Answer 1

看來你的 Flutter 安裝有問題。 您可以嘗試重新安裝它（確保您獲得了適用於您的操作系統的版本）。 第二個問題是Android SDK。 安裝 Android Studio 是不夠的。 嘗試完成此設置說明： https : //flutter.dev/docs/get-started/install#android-setup 。
