当我在 flutter web 项目中添加一些像 ListView 这样的小部件时，我遇到了这个错误，我以前在使用 android 时从未遇到过这个错误

我到处找，但没有任何线索，提前致谢

当我构建项目时,我收到以下错误错误:SSL对等关闭错误请告诉我如何解决此错误

这个问题已经被问了两次，但没有答案小米设备上安装的应用程序需要一个名为“在锁定屏幕上显示”的权限，以便在设备被锁定时启动活动 如何提示用户在 android 中以编程方式启用此权限工作室，一些消息应用程序，如 Messenger、Telegram、Whatapp 已经启用了此权限我已经添加了这四个标志，但如果未授予权限，则不会显示活动

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON|
            WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD|
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED|
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

提前致谢

我到处搜索，但找不到这个问题的答案，如果启用了 Firebase 持久性，如果设备处于离线状态，应用程序会在设备重新连接后继续同步数据，但我的问题是，如果设备重新启动，firebase 会不会在获得连接后自动同步数据，或者我应该使用广播接收器来检测系统重启以使其正常工作.....
