android - Flutter 构建问题：Dart 快照生成器失败，退出代码为 -9

问题描述

构建颤振 apk 或 appbundle 时出现以下异常。它随机发生。我不知道是什么触发了它。我该如何进一步调试呢？

Dart snapshot generator failed with exit code -9

解决方案

我有同样的问题，它解决的是使用来自其他类的静态变量而不是通过创建实例：

工作正常：

import file
ClassName.variable

漏洞：

import file
var instance = ClassName()
instance.variable
