  # 配置全局的Javahome地址。
  flutter config --jdk-dir=/Volumes/extend/tools/jdk-11.0.24.jdk/Contents/Home

修改成功之后展示的路径

flutter doctor -v 
[!] Android toolchain - develop for Android devices (Android SDK version 34.0.0)
    • Android SDK at /Volumes/extend/tools/Android/sdk
    • Platform android-34, build-tools 34.0.0
    • ANDROID_HOME = /Volumes/extend/tools/Android/sdk
    • Java binary at: /Volumes/extend/tools/jdk-11.0.24.jdk/Contents/Home/bin/java
    • Java version Java(TM) SE Runtime Environment 18.9 (build 11.0.24+7-LTS-271)
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/to/macos-android-setup for more details.

需要配置删除的话可以执行空内容

flutter % flutter config --jdk-dir=
Removing "jdk-dir" value.

You may need to restart any open editors for them to read new settings.

默认情况下，flutter读取的是电脑配置默认的android studio中的Java的版本
