│ If you recently upgraded Android Studio, consult the migration guide at │

│ │
│ Otherwise, to fix this issue, first, check the Java version used by Flutter by running flutter │ │ doctor --verbose. │
│ │
│ Then, update the Gradle version specified in │

这不是说得很清楚了，你运行 Gradle 的 Java 版本和 Gradle 支持的版本不匹配

@yiyiniu 就按照上面日志的 Flutter fix 里写的操作啊。先看看你的 Gradle 是什么版本，然后对照 Compatibility Matrix 看看需要什么 Java 版本。Java 21 只有 Gradle 8.4 以后才支持，要么升级 Gradle ，要么降级 Java
