Flutter 添加Connectivity后无法发布或调试

Question

此问题的解决方案 我删除了 JDK 13。我安装了 JDK 8。我给了 Flutter SDK 的环境变量。在用户变量中扑 C:\flutter\bin

我给了JAVA_HOME的环境变量。在系统变量中 JAVA_HOME C:\Program Files\Java\jdk1.8.0_241

然后我用 cmd 接受了 Android 许可。 (flutter doctor --android-licenses)

现在我可以使用 flutter 连接了。问题已经解决了。谢谢。

---------------------------------------- ----------

当我将连接添加到我的应用程序时，我无法调试或发布到我的应用程序 pubspec.yaml

Answer 1

您需要在 Mac 中以您的用户名创建一个全局文件。只需创建一个 .bash_profile 文件，如下所述：

Open to see location and locate your flutter sdk inside.

我删除了 JDK 13.我安装了 JDK 8.

我给了Flutter SDK的环境变量。在用户变量中扑 C:\flutter\bin

我给了JAVA_HOME的环境变量。在系统变量中 JAVA_HOME C:\Program Files\Java\jdk1.8.0_241
