I bet you'll be able to see the issue, but there's a chance it will fool even you, the owners. Try to focus on the error message, rather than the command.

~/dart/flutter φ sdkmanager install 'system-images;android-25;google_apis_playstore;x86'
Warning: Failed to find package install

If you *did* fall for the same trap that I did, then your brain inserted the word "to" between "package" and "install", ie, "Warning: cannot find package *to* install". This leaves me nothing to go on, granted, its an illusion!

Three things of note:

1. "sdkmanager foo" being a command to install the package foo (which isn't even an sdk)...is confusing
2. putting quotes around the package name for this error would break the brain illusion.
3. Why is this a warning? The whole installation process did nothing. That seems bigger than a warning.

Didn't see anyone else on stack overflow or anything hitting this, but I think #2 is going to hit other users.

With the fix it would be

Warning: Failed to find package "install"

which is much clearer.
