flutter_background_geolocation 在发布模式下不起作用

Question

我设置了所有内容，没有跳过这个插件的任何一点。它可以在所有调试模式下工作（前台、后台、Kill stat）。

错误日志：在发布模式下终止应用程序时

Answer 1

这似乎是 Flutter 3.3 中的一个问题，它破坏了隔离中运行的插件。

您需要使用 @pragma('vm:entry-point') 注释在隔离中运行的顶级或静态函数

像这样

@pragma('vm:entry-point')
void locationCallback() {
  .......
  });

}
