我正在尝试将 firebase 消息集成到我的颤振应用程序中。在 Android 上它可以完美运行，但在 Ios 中，在构建应用程序时，它会打开一个白屏，并且没有其他任何内容出现。

我只能成功运行该应用程序一次，其中一个请求似乎从 Firebase 接收推送消息，即使在我能够发送通知之前也是如此。

我卸载了该应用程序并尝试再次安装，之后它只停留在白屏上，并且 Ios 不再发出请求发送推送权限的通知。

在 X-code Capabilities 中，我启用了推送通知和后台模式“后台获取”和“远程通知”

有没有人经历过这个？

尝试降级您的 firebase_messaging 插件以及 firebase_core
