Upgrade 1.3 -> 2.1 swc FillSymbol not found

[BrendanCollins]

Hey Everybody,

I am upgrading an application from the 1.3 swc to 2.1 and am getting:

"Type was not found or was not a compile-time constant: FillSymbol"

The location is unknown.  I have set the SDK to 4.0.

Thanks in advance for any advice.

The symbol package was renamed to symbols. For more info, see:

Hey thanks a lot...I think I found a problem in an older swc. Thanks
