I can only generate a build when I clear the cache

It looks like the flutter installation cache folder is broken.
rm -rf / Users/macuser/Programs/flutter/bin/cache

The build works when you clear the cache? If so that's odd unless you changed the app in the meantime. Looks like you're trying to build your own application that depends on SpeechToText, not the included example? It is true that the SpeechToText plugin only supports iOS 10 or later.

Looks like I should add the guard conditions so that I don't block other applications that want to support lower versions. I'll look at those changes. Thanks for the report.

So I had a look, it is possible to make it support lower versions but it makes the code significantly less readable and given that I can't even get a simulator below iOS 10 anymore I don't think there's a market for it. I think that it is probably better for the plugin to leave it at iOS 10 and require any applications that use it to set their minimum iOS version to 10 or above. Please let me know if that causes problems.

If you're curious there's a version of the plugin code in the iOS-8 branch of the repo. Feel free to try it out if you'd like. Because it doesn't have the @available 10 check around the plugin it won't throw the unguarded availability check at compile time. However I haven't been able to test it on an old OS. If there's sufficient demand I'll look at adding it to master.

The latest commit changes the Podfile for the example to declare iOS 10 which removes the unguarded warning. I'm going to close this until I get more feedback on a need for support below iOS 10.
