FAILURE：构建失败并出现异常。

• 其中：脚本 'C:\src\flutter\flutter\packages\flutter_tools\gradle\flutter.gradle' 行：896

• 出了什么问题：任务“：app：compileFlutterBuildDebug”执行失败。

Process 'command 'C:\src\flutter\flutter\bin\flutter.bat'' 以非零退出值 1 结束

• 尝试：使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。
