Flutter IOS上的颤振版本停留在1.0.0

当我跑步时：

pod outdated

在IOS上，要确定任何过时的POD，我会得到以下结果：

.... 

Analyzing dependencies
The color indicates what happens when you run `pod update`
<green>  - Will be updated to the newest version
<blue>   - Will be updated, but not to the newest version because of specified version in Podfile
<red>    - Will not be updated because of specified version in Podfile

The following pod updates are available:
- Flutter 1.0.0 -> 1.0.0 (latest version 1.3.300)
- Protobuf 3.9.2 -> 3.9.2 (latest version 3.10.0-rc1)

上述命令似乎对上述pod版本没有影响。我希望一切都是最新的版本，但如果没有必要知道这些信息也会很有帮助

使用：

/Users/bob/Downloads/flutter/bin/flutter doctor -v

我现在正在测试这一点，但如果您导航到

app\u project/ios/flatter/flatter.podspec

，您将看到flatter版本硬编码为1.0.0

现在我不是颤振方面的专家，所以我不知道您是否应该手动更改此文件，您应该将其更改为什么版本，是否有任何区别，以及为什么在执行颤振升级时颤振不提供脚本来同时更新此文件和颤振版本。

有关于此问题的更新吗？我也有同样的问题。
