【问题描述】：

我刚刚复制粘贴了示例代码以开始使用 Firebase 电话身份验证。但是 firebase 不会向真实号码和测试号码发送 SMS 代码。我对两者都进行了测试。你能帮忙找出问题吗？

这是 Flutter Doctor 的输出

请帮我解决这个问题。

【问题讨论】：

你在模拟器上测试它吗？
不，它是真实设备。我已经实现了这个。但是这次没有发送短信，控制台也没有显示消息消息。

【解决方案1】：

问题出在火力基地本身。那天它没有发送任何短信。现在相同的代码运行良好。

【讨论】：

相同的火力基地不发送任何短信。代码发送回调被调用，但 firebase 没有发送任何短信。
